Subject: [PATCH 1/3] Add AI spell correction trigger hook in InputLogic

After a sentence-ending punctuation character (. ! ? ...) is committed to the
InputConnection, notify AiTriggerHook with the text before the cursor so the
AI correction engine can run in the background.

Field name confirmed: mLatinIME (type LatinIME, first constructor parameter).
The hook is debounced (500ms) and async — the IME main thread is never blocked.
