This pull request refactors and centralizes the logic for watching Python package changes across different environment managers (system, conda, poetry). The new approach introduces a shared utility to handle file system watching for package metadata, ensuring more robust and consistent package refresh behavior when environments change.

Key improvements and changes:

Centralized Package Watcher Logic:

• Added a new module, packageWatcher.ts, which provides watchPackageChangesForEnvironment and registerPackageWatcherForManager to handle file watching and package refresh for any environment manager. This replaces duplicated logic in each manager.

Refactoring of Environment Managers:

• Updated main.ts files for system, conda, and poetry managers to use the new registerPackageWatcherForManager function, removing their own package watcher and debounce logic. This simplifies each manager and ensures consistency. [1] [2] [3] [4] [5] [6]

Improved Robustness and Maintainability:

• The new watcher logic automatically tracks the active environment, ensuring watchers are always up-to-date and resources are cleaned up appropriately.

Platform and Environment Awareness:

• The watcher targets are now tailored to different platforms (Windows, Unix) and environment types (including conda), ensuring accurate detection of package changes.
