Windows Store Python support

[ShaikhWarsi]

Fixes #57

Key Changes

• New Installer Plugin : Added MicrosoftStoreInstaller in standard.py which uses winget to handle installations and uninstallations from the Microsoft Store.
• Improved Detection : Updated version.py to identify Store versions by parsing py --list output and scanning %LOCALAPPDATA%\Microsoft\WindowsApps .
• TUI Enhancements : Added a "Store" label in tui.py to clearly distinguish Store-installed versions from standard ones in the UI.
• CLI Integration : Enabled the --installer store flag for manual control over Store installations via the CLI

Good feature implementation for Microsoft Store Python support! The detection logic and TUI integration look solid. However, there's a critical issue that prevents the plugin from working.

Critical Bug: Plugin Not Registered

The MicrosoftStoreInstaller class is created in standard.py, but it's never registered in plugins/manager.py. The plugin will not be loaded or available.
You need to update plugins/manager.py:
1. Add the import:

from .standard import (
    AptInstaller,
    AsdfInstaller,
    BrewInstaller,
    CondaInstaller,
    MicrosoftStoreInstaller,  # <-- Add this
    MiseInstaller,
    PyenvInstaller,
    SourceInstaller,
    WindowsInstaller,
)

2. Register in _register_builtins():

def _register_builtins(self) -> None:
    builtins = [
        MiseInstaller(),
        AsdfInstaller(),
        PyenvInstaller(),
        BrewInstaller(),
        CondaInstaller(),
        AptInstaller(),
        MicrosoftStoreInstaller(),  # <-- Add this
        WindowsInstaller(),
        SourceInstaller(),
    ]

Other Notes (non-blocking)

1. Tests would be helpful - especially for the Store version detection logic in version.py
2. Consider squashing commits - There are 18 commits with many "Add files via upload" and repeated pycache deletions. A cleaner history would be nice, but not required.
3. Good priority choice - Priority 75 (between mise/pyenv at 90-100 and WindowsInstaller at 60) makes sense for Store installations.
   What looks good

• Store version detection via py --list parsing
• Fallback scanning of %LOCALAPPDATA%\Microsoft\WindowsApps
• TUI properly shows "Store" label
• Uninstall support via winget
• Tries multiple package ID patterns (Python.Python.X.Y and PythonSoftwareFoundation.Python.X.Y)

Please add the plugin registration and this is good to merge!

All previous feedback has been addressed:

• Plugin now properly imported and registered in manager.py
• Comprehensive tests added (test_store_detection.py)
  The implementation is solid:
• MicrosoftStoreInstaller properly integrated with plugin system
• Priority 75 makes sense (higher than direct installer, lower than version managers)
• Fallback to alternate package ID patterns (Python.Python.X.Y and PythonSoftwareFoundation.Python.X.Y)
• Store version detection via both py --list and WindowsApps path scanning
• Path info properly merged when detected from multiple sources
• TUI properly displays "Store" label
• Good test coverage for detection logic
  LGTM!
