Refactor: Standardize PackageManager

[edvilme]

This pull request introduces a new GetPackagesOptions interface to support additional options (such as cache bypassing) when retrieving Python packages from a given environment. It updates the relevant APIs, interfaces, and implementations to accept this new options parameter, and refactors the pip package manager logic to support cache skipping and code simplification. The changes are applied consistently across the main codebase and sample/example files.

API and Interface Enhancements:

• Added a new GetPackagesOptions interface, allowing callers to specify options (currently skipCache) when retrieving packages. This is now accepted by getPackages methods in PackageManager and PythonPackageGetterApi interfaces. [1] [2] [3] [4] [5] [6] [7] [8]

• Updated all usages and implementations of getPackages to accept the new optional options parameter, including in PythonEnvironmentApiImpl, InternalPackageManager, and related example/sample APIs. [1] [2] [3] [4]

Pip Package Manager Refactoring and Improvements:

• Renamed pipManager.ts to pipPackageManager.ts and updated imports accordingly.

• Refactored the pip package manager to support cache bypassing: if options.skipCache is set, it fetches a fresh package list instead of using the cache. Also simplified the logic for managing and refreshing packages, delegating change notification to a new shared utility. [1] [2] [3]

• Removed redundant code for change detection and replaced with a shared updatePackagesAndNotify utility. [1] [2] [3]

Utilities and Supporting Changes:

• Refactored pip package refresh utilities: replaced the raw refresh logic with a more flexible function (execPipList) that supports additional arguments, and removed now-unnecessary helper functions. [1] [2] [3] [4]

Code Style and Minor Cleanups:

• Minor formatting and code style updates across example/sample API files for consistency. [1] [2] [3] [4] [5] [6] [7]

These changes improve the flexibility and maintainability of the package management APIs and their implementations, preparing the codebase for future enhancements and better cache control.

These refactorings make adding new features to the Package Managers (e.g., #1530) much easier by properly delegating responsibilities and using clear API names.

This one I will need to consider more as they adjust the api surface. I would be more comfortable with a change where we instead added an optional arg to the get or manage packages that allowed you to specify if it should refresh cache. So we have the same surface generally just allows someone to specify what type of change it should be as it relates to the cache. What are your thoughts on a design like this?

just the one question but overall looks good!!
