Boliang Zhang 5ec457ea44 fix(shortcutguide): restore excluded-app filtering regression (#50046)
## Summary of the Pull Request

**Regression:** PR #48683 changed Shortcut Guide from a process launched
per invocation to a
persistent background process. Before that change, every activation
started a process and evaluated
the current foreground app against the latest excluded-app settings. The
excluded-app check
remained in `Program.Main`, so after #48683 it ran only when the
persistent process started.
Excluded apps therefore stopped blocking later regular-hotkey and
Windows-key-hold activations, and
newly saved exclusions had no effect until the process was recycled.

This PR restores the pre-#48683 excluded-app behavior by:

- starting the persistent Shortcut Guide listener regardless of the
startup foreground app;
- evaluating the current foreground app against the latest excluded-app
settings before each
  hidden-overlay activation;
- applying the same gate to the regular hotkey and Windows-key-hold
paths; and
- preserving close and hold-surface promotion behavior when the overlay
is already visible.

## PR Checklist

- [x] Closes: #50030
- [ ] **Communication:** This regression was diagnosed from the issue
and recent Shortcut Guide
lifecycle changes; it has not yet been discussed with core contributors
- [x] **Tests:** Added/updated and all pass
- [x] **Localization:** N/A - no end-user-facing strings were added or
changed
- [x] **Dev docs:** N/A - no public behavior or developer contract
changed
- [x] **New binaries:** N/A - no binaries or projects were added
- [x] **Documentation updated:** N/A - this is a regression fix
restoring existing behavior

## Detailed Description of the Pull Request / Additional comments

`src/modules/ShortcutGuide/ShortcutGuide.Ui/Program.cs` no longer exits
at process startup when the
then-foreground application is excluded. The background listener must
remain available for later
activations.


`src/modules/ShortcutGuide/ShortcutGuide.Ui/ShortcutGuideXAML/App.xaml.cs`
calls the existing native
excluded-app helper for each activation while the overlay is hidden.
That helper already reloads
`settings.json` and rebuilds its excluded-app list on every call, so no
watcher or cache is needed.
The result is passed into

`src/modules/ShortcutGuide/ShortcutGuide.Ui/Helpers/ShortcutGuideActivationPolicy.cs`,
keeping the
decision shared by both activation sources and directly testable.

The check is intentionally skipped while the overlay is visible. This
preserves the regular
hotkey's ability to close its guide or take ownership of a guide opened
by Windows-key hold.
Suppression logging is generic and does not include application names,
paths, window titles, or
settings content.

This is a regression fix rather than a new excluded-app feature or
settings-schema change.

## Validation Steps Performed

- Built
`src/modules/ShortcutGuide/ShortcutGuide.UnitTests/ShortcutGuide.UnitTests.csproj`
for x64
  Release from the final rebased commit.
- Ran the Shortcut Guide test executable: **48 passed, 0 failed, 0
skipped**.
- Added cases covering:
  - regular-hotkey suppression over an excluded app;
- Windows-key-hold suppression for taskbar indicators and the full
guide;
  - closing a visible regular guide; and
  - promoting visible hold indicators with the regular hotkey.
- Built a complete local x64 Release payload and confirmed its Runner
launched the local Shortcut
  Guide process and handled open/close activation.
