fix(windows): allow synthetic hotkeys to trigger OpenLess

[H-Chris233]

Summary\n\n- Remove the LLKHF_INJECTED filter so SendInput, keybd_event, and virtual keyboard tools reach the normal OpenLess hotkey dispatcher.\n- Keep configured-hotkey matching, down/up edge de-duplication, left/right modifier separation, combo cancellation, and held-state cleanup on reload/exit.\n- Fix the no-ASR stop path so the capsule is hidden after dry-run or ASR initialization failure.\n- Update Windows smoke scripts to use complete down/up cycles, release all modifiers in inally, and cover 20 iterations each for keybd_event and SendInput.\n- Make smoke tests independent of persisted local hotkey mode and skip the Windows symlink assertion only when error 1314 means the test environment lacks symlink privilege.\n\n## Validation\n\n- Rust tests: 1150 passed, 0 failed\n- cargo build: passed\n- Frontend

pm test: 48 passed\n- Windows keybd_event smoke: 20/20\n- Windows SendInput smoke: 20/20\n- Capsule lifecycle smoke: passed\n- PowerShell smoke AST checks: passed\n- git diff --check: passed\n\nThe Windows release build was attempted but blocked during the third-party oundry-local-sdk build script/native dependency download stage; no unrelated dependency changes were made.\n\n## Scope\n\nThis intentionally accepts synthetic low-level keyboard events from any source, while only configured hotkeys trigger OpenLess. PostMessage(WM_KEYDOWN) and Windows security-desktop/integrity-boundary restrictions remain outside the low-level hook path.\n\n## Checklist\n\n- [x] Synthetic RightControl events accepted by the low-level hook\n- [x] Duplicate down/up and modifier state handling covered\n- [x] Ctrl+A, Alt+Tab, and ordinary unrelated keys remain guarded by existing matching logic\n- [x] Modifier cleanup added to smoke failure paths\n- [ ] Windows release build (blocked by third-party SDK download/build stage)
