Improve desktop runtime execution tests

Test improvements:

- Capture titles for all macOS windows, not just the frontmost.
- Incorporate missing application log files.
- Improve log clarity with enriched context.
- Improve application termination on macOS by reducing grace period.
- Ensure complete application termination on macOS.
- Validate Vue application loading through an initial log.
- Support ignoring environment-specific `stderr` errors.
- Do not fail the test if working directory cannot be deleted.
- Use retry pattern when installing dependencies due to network errors.

Refactorings:

- Migrate the test code to TypeScript.
- Replace deprecated `rmdir` with `rm` for error-resistant directory
  removal.
- Improve sanity checking by shifting from App.vue to Vue bootstrapper.
- Centralize environment variable management with `EnvironmentVariables`
  construct.
- Rename infrastructure/Environment to RuntimeEnvironment for clarity.
- Isolate WindowVariables and SystemOperations from RuntimeEnvironment.
- Inject logging via preloader.
- Correct mislabeled RuntimeSanity tests.

Configuration:

- Introduce `npm run check:desktop` for simplified execution.
- Omit `console.log` override due to `nodeIntegration` restrictions and
  reveal logging functionality using context-bridging.
