666f1b400e fix: non-blocking XPending event loop + auto re-grab on grab loss 
- Use XPending() to check for events before XNextEvent (non-blocking)
- Add is_grabbed() and has_pending_events() public methods
- Auto re-grab keyboard when grab is silently lost (tray, WM focus)
- Fixes AppImage daemon receiving zero keystroke events

3858aa955c feat: implement Backspace-Replay pattern for perfect engine sync 
- Add Engine::replay_keystrokes() — creates fresh engine and replays
  all keystrokes to compute correct screen output from scratch
- Add Daemon::replay_and_inject() — tracks keystroke history and
  screen output, computes diff (backspaces + new text) on each keypress
- Add Daemon::replay_backspace() — pops from history, replays, diffs
- Handle flush chars (space, period, etc.) separately — commit word,
  type char, clear history
- Add FocusIn/FocusOut detection for engine reset on focus loss
- Add CPU pinning (P-cores 0-3) + nice(-10) priority boost
- Clean up 9 dead code warnings (unused fields, constants, types)
- Add replay_keystrokes tests for Telex, VNI, and backspace
- 255 tests pass (was 252)

bb0847a38f X11 capture: proper key tracking, direct clipboard, VNI default 
- X11 keyboard capture via XGrabKeyboard (no input group needed)
- Direct X11 clipboard for Unicode injection (no xclip/xdotool dependency)
- Proper KeyPress/KeyRelease tracking (fix Ctrl+C, Alt+Tab, held keys)
- Default input_method=vni, start_enabled=false
- AppImage: bundled xclip, proper keyboard+VN SVG icon
- Deb: Recommends libxtst6, xclip

42595d4bae Fix backspace in grab mode: inject KEY_BACKSPACE via uinput 
When grab is enabled, the physical key is intercepted by evdev grab.
The engine's pop() updates the buffer but the KEY_BACKSPACE was never
injected — send_char('\x08') can't emit a keycode and fell through to
paste_string. Now backspace injects KEY_BACKSPACE press+release via
uinput directly.

cdb5eb4812 Improve engine: tone placement, backtrack limit, grab default 
- Fix tone placement for uâ, uê, uơ → tone on second vowel (e.g. tuấn, thuế, phương)
- Limit flexible backward scan to 3 chars to prevent cross-syllable modification
- Set grab = true as default config
- Add 9 new engine tests for tone placement and backtrack limit

44a4b032a6 Fix injection: skip ydotool for Unicode, use xdotool/xclip 
- Simplify inject_replacement_atomic: backspaces via uinput always
- paste_string skips ydotool for non-ASCII text (crashes with 'no matching keycode')
- Use xdotool (X11) or clipboard (xclip) for Vietnamese characters
- Add detailed logging at EVERY fallback step
- Remove dead ydotoold auto-start code (not available in Ubuntu package)

c3bc35ddce Fix garbled text: correct AppRun Wayland detection + atomic injection 
- AppRun no longer sets WAYLAND_DISPLAY on X11 (checks for wayland socket)
- execute_commands now uses ydotool for both backspaces+text (same device)
- Merged execute_commands and execute_commands_with_grab into one function
- grab defaults to true in AppImage config
