Quick Shell for CmdPal ทุกเวอร์ชันและเวอร์ชันเก่า

### Changed

- Much smaller Command Palette package: Release MSIX is roughly ~30 MB after trim (down from ~126 MB) by dropping WinForms and stripping unused framework code, so installs and updates download less.
- Snappier search and list refresh by cutting allocations on hot paths (task search tokens, PATH lookups, display text, health-check parsing).
- Faster workspace suggestions and home-row enrichment with less redundant work while you browse and launch.
- Quicker terminal profile icon loading via Windows Terminal fragment discovery, icon resizing, and skip-reparse when fragment files have not changed.
- Smoother status and branch-picker refresh when drives come back online or a load fails (retryable errors, no stuck duplicate loads).

### Fixed

- Profile icons from Windows Terminal fragments (including relative paths and fragment `updates`) resolve more reliably.
- Blank `.ico` sources are handled without breaking valid PNG icons.
- Offline or repaired workspace folders re-probe after a short TTL instead of staying stuck until restart.
