Introduce new TreeView UI component

Key highlights:

- Written from scratch to cater specifically to privacy.sexy's
  needs and requirements.
- The visual look mimics the previous component with minimal changes,
  but its internal code is completely rewritten.
- Lays groundwork for future functionalities like the "expand all"
  button a flat view mode as discussed in #158.
- Facilitates the transition to Vue 3 by omitting the Vue 2.0 dependent
  `liquour-tree` as part of #230.

Improvements and features:

- Caching for quicker node queries.
- Gradual rendering of nodes that introduces a noticable boost in
  performance, particularly during search/filtering.
  - `TreeView` solely governs the check states of branch nodes.

Changes:

- Keyboard interactions now alter the background color to highlight the
  focused item. Previously, it was changing the color of the text.
- Better state management with clear separation of concerns:
  - `TreeView` exclusively manages indeterminate states.
  - `TreeView` solely governs the check states of branch nodes.
  - Introduce transaction pattern to update state in batches to minimize
    amount of events handled.
- Improve keyboard focus, style background instead of foreground. Use
  hover/touch color on keyboard focus.
- `SelectableTree` has been removed. Instead, `TreeView` is now directly
  integrated with `ScriptsTree`.
- `ScriptsTree` has been refactored to incorporate hooks for clearer
  code and separation of duties.
- Adopt Vue-idiomatic bindings instead of keeping a reference of the
  tree component.
- Simplify and change filter event management.
- Abandon global styles in favor of class-scoped styles.
- Use global mixins with descriptive names to clarify indended
  functionality.

 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
 
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
 
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
 
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under

+## Desktop builds
+
+Desktop builds uses `electron-vite` to bundle the code, and `electron-builder` to build and publish the packages.
+
+## Styles
+
+### Style location
+
+- **Global styles**: The [`assets/styles/`](#structure) directory is reserved for styles that have a broader scope, affecting multiple components or entire layouts. They are generic and should not be tightly coupled to a specific component's functionality.
+- **Component-specific styles**: Styles closely tied to a particular component's functionality or appearance should reside near the component they are used by. This makes it easier to locate and modify styles when working on a specific component.
+
+### Sass naming convention
 
 - Use lowercase for variables/functions/mixins, e.g.:
   - Variable: `$variable: value;`

@@ -5,78 +5,79 @@ There are different types of tests executed:
 1. [Unit tests](#unit-tests)
 2. [Integration tests](#integration-tests)
 3. [End-to-end (E2E) tests](#e2e-tests)
+4. [Automated checks](#automated-checks)
 
-Common aspects for all tests:
+## Unit and integration tests
 
-- They use [Mocha](https://mochajs.org/) and [Chai](https://www.chaijs.com/).
-- Their files end with `.spec.{ts|js}` suffix.
-
-💡 You can use path/module alias `@/tests` in import statements.
-
-## Unit tests
-
-- Unit tests test each component in isolation.
-- All unit tests goes under [`./tests/unit`](./../tests/unit).
-- They rely on [stubs](./../tests/unit/shared/Stubs) for isolation.
-- Unit tests include also Vue component tests using `@vue/test-utils`.
-
-### Unit tests structure
-
-- [`./src/`](./../src/)
-  - Includes source code that unit tests will test.
-- [`./tests/unit/`](./../tests/unit/)
-  - Includes test code.
-  - Tests follow same folder structure as [`./src/`](./../src).
-    - E.g. if system under test lies in [`./src/application/ApplicationFactory.ts`](./../src/application/ApplicationFactory.ts) then its tests would be in test would be at [`./tests/unit/application/ApplicationFactory.spec.ts`](./../tests/unit/application/ApplicationFactory.spec.ts).
-  - [`shared/`](./../tests/unit/shared/)
-    - Includes common functionality that's shared across unit tests.
-    - [`Assertions/`](./../tests/unit/shared/Assertions):
-      - Common assertions that extend [Chai Assertion Library](https://www.chaijs.com/).
-      - Asserting functions should start with `expect` prefix.
-    - [`TestCases/`](./../tests/unit/shared/TestCases/)
-      - Shared test cases.
-      - Functions that calls `it()` from [Mocha test framework](https://mochajs.org/) should have `it` prefix.
-        - E.g. `itEachAbsentCollectionValue()`.
-    - [`Stubs/`](./../tests/unit/shared/Stubs)
-      - Includes stubs to be able to test components in isolation.
-      - Stubs have minimal and dummy behavior to be functional, they may also have spying or mocking functions.
-
-### Unit tests naming
-
-- Each test suite first describe the system under test.
-  - E.g. tests for class `Application.ts` are all inside `Application.spec.ts`.
-- `describe` blocks tests for same function (if applicable).
-  - E.g. test for `run()` are inside `describe('run', () => ..)`.
+- They utilize [Vitest](https://vitest.dev/).
+- Test files are suffixed with `.spec.ts`.
 
 ### Act, arrange, assert
 
-- Tests use act, arrange and assert (AAA) pattern when applicable.
+- Tests implement the act, arrange, and assert (AAA) pattern.
 - **Arrange**
-  - Sets up the test case.
-  - Starts with comment line `// arrange`.
+  - Sets up the test scenario and environment.
+  - Begins with comment line `// arrange`.
 - **Act**
   - Executes the actual test.
-  - Starts with comment line `// act`.
+  - Begins with comment line `// act`.
 - **Assert**
-  - Elicit some sort of expectation.
-  - Starts with comment line `// assert`.
+  - Sets an expectation for the test's outcome.
+  - Begins with comment line `// assert`.
 
-## Integration tests
+### Unit tests
 
-- Tests functionality of a component in combination with others (not isolated).
-- Ensure dependencies to third parties work as expected.
-- Defined in [./tests/integration](./../tests/integration).
+- Evaluate individual components in isolation.
+- Located in [`./tests/unit`](./../tests/unit).
+- Achieve isolation using [stubs](./../tests/unit/shared/Stubs).
+- Include Vue component tests, enabled by `@vue/test-utils`.
+
+#### Unit tests naming
+
+- Test suites start with a description of the component or system under test.
+  - E.g., tests for `Application.ts` are contained in `Application.spec.ts`.
+- Whenever possible, `describe` blocks group tests of the same function.
+  - E.g., tests for `run()` are inside `describe('run', () => ...)`.
+
+### Integration tests
+
+- Assess the combined functionality of components.
+- They verify that third-party dependencies function as anticipated.
 
 ## E2E tests
 
-- Test the functionality and performance of a running application.
-- Vue CLI plugin  [`e2e-cypress`](https://github.com/vuejs/vue-cli/tree/dev/packages/@vue/cli-plugin-e2e-cypress#readme) configures E2E tests.
-- Test names and folders have logical structure based on tests executed.
-- The structure is following:
-  - [`cypress.config.ts`](./../cypress.config.ts): Cypress configuration file.
-  - [`./tests/e2e/`](./../tests/e2e/): Base Cypress folder.
-    - [`/specs/`](./../tests/e2e/specs/): Test files named with `.spec.js` extension.
-    - [`/plugins/index.js`](./../tests/e2e/plugins/index.js): Plugin file executed before loading project.
-    - [`/support/index.js`](./../tests/e2e/support/index.js): Support file, runs before every single spec file.
-    - *(Ignored)* `/videos`: Asset folder for videos taken during tests.
-    - *(Ignored)* `/screenshots`: Asset folder for Screenshots taken during tests.
+- Examine the live web application's functionality and performance.
+- Uses Cypress to run the tests.
+
+## Automated checks
+
+These checks validate various qualities like runtime execution, building process, security testing, etc.
+
+- Use [various tools](./../package.json) and [scripts](./../scripts).
+- Are automatically executed as [GitHub workflows](./../.github/workflows).
+
+## Tests structure
+
+- [`package.json`](./../package.json): Defines test commands and includes tools used in tests.
+- [`vite.config.ts`](./../vite.config.ts): Configures `vitest` for unit and integration tests.
+- [`./src/`](./../src/): Contains the code subject to testing.
+- [`./tests/shared/`](./../tests/shared/): Contains code shared by different test categories.
+  - [`bootstrap/setup.ts`](./../tests/shared/bootstrap/setup.ts): Initializes unit and integration tests.
+- [`./tests/unit/`](./../tests/unit/)
+  - Stores unit test code.
+  - The directory structure mirrors [`./src/`](./../src).
+    - E.g., tests for [`./src/application/ApplicationFactory.ts`](./../src/application/ApplicationFactory.ts) reside in [`./tests/unit/application/ApplicationFactory.spec.ts`](./../tests/unit/application/ApplicationFactory.spec.ts).
+  - [`shared/`](./../tests/unit/shared/)
+    - Contains shared unit test functionalities.
+    - [`Assertions/`](./../tests/unit/shared/Assertions): Contains common assertion functions, prefixed with `expect`.
+    - [`TestCases/`](./../tests/unit/shared/TestCases/)
+      - Shared test cases.
+      - Functions that calls `it()` from [Vitest](https://vitest.dev/) should have `it` prefix.
+    - [`Stubs/`](./../tests/unit/shared/Stubs): Maintains stubs for component isolation, equipped with basic functionalities and, when necessary, spying or mocking capabilities.
+- [`./tests/integration/`](./../tests/integration/): Contains integration test files.
+- [`cypress.config.ts`](./../cypress.config.ts): Cypress (E2E tests) configuration file.
+- [`./tests/e2e/`](./../tests/e2e/): Base Cypress folder, includes tests with `.cy.ts` extension.
+  - [`/support/e2e.ts`](./../tests/e2e/support/e2e.ts): Support file, runs before every single spec file.
+  - [`/tsconfig.json`]: TypeScript configuration for file Cypress code, improves IDE support, recommended to have by official documentation.
+  - *(git ignored)* `/videos`: Asset folder for videos taken during tests.
+  - *(git ignored)* `/screenshots`: Asset folder for Screenshots taken during tests.

+Description:
+  This script manages NPM dependencies for a project.
+  It offers capabilities like doing a fresh install, retries on network errors, and other features.
+
+Usage:
+  npm run install-deps [-- <options>]
+  node scripts/npm-install.js [options]
+
+Options:
+  --root-directory <path>
+    Specifies the root directory where package.json resides
+    Defaults to the current working directory.
+    Example: npm run install-deps -- --root-directory /your/path/here
+
+  --no-errors
+    Ignores errors and continues the execution.
+    Example: npm run install-deps -- --no-errors
+
+  --ci
+    Uses 'npm ci' for dependency installation instead of 'npm install'.
+    Example: npm run install-deps -- --ci
+
+  --fresh
+    Removes the existing node_modules directory before installing dependencies.
+    Example: npm run install-deps -- --fresh
+
+  --non-deterministic
+    Removes package-lock.json for a non-deterministic installation.
+    Example: npm run install-deps -- --non-deterministic
+
+Note:
+
+  Flags can be combined as needed.
+  Example: npm run install-deps -- --fresh --non-deterministic

+      This script either creates or updates the `user.js` file to set specific Mozilla Firefox preferences.
+
+      The `user.js` file can be found in a Firefox profile folder [1] and its location depends on the type of installation:
+    
+      - Default: `~/.mozilla/firefox/<profile-name>/user.js`
+      - Flatpak: `~/.var/app/org.mozilla.firefox/.mozilla/firefox/<profile-name>/user.js`
+      - Snap: `~/snap/firefox/common/.mozilla/firefox/<profile-name>/user.js`
+    
+      While the `user.js` file is optional [2], if it's present, the Firefox application will prioritize its settings over
+      those in `prefs.js` upon startup [1][2]. To prevent potential profile corruption, Mozilla advises against editing
+      `prefs.js` directly [2].
