This commit improves the dependency injection mechanism by introducing a custom `injectKey` function. Key improvements are: - Enforced type consistency during dependency registration and instantiation. - Simplified injection process, abstracting away the complexity with a uniform API, regardless of the dependency's lifetime. - Eliminated the possibility of `undefined` returns during dependency injection, promoting fail-fast behavior. - Removed the necessity for type casting to `symbol` for injection keys in unit tests by using existing types. - Consalidated imports, combining keys and injection functions in one `import` statement.
