nova aa8fff2c0d Initial commit: HeliBoard + Gemma 4 on-device AI correction
Integrates LiteRT-LM (Google) with Gemma 4 E2B-it for on-device
spell/grammar correction in HeliBoard. After sentence-ending punctuation,
the model checks the sentence and shows a correction in the suggestion strip.
Tapping it replaces the original text — fully offline, no cloud API.

Subject: [PATCH 3/3] Add italic colour styling for AI correction suggestions
Modifies two methods in SuggestionStripLayoutHelper:
1. getSuggestionTextColor(): Returns mColorAutoCorrect for AI suggestions
(KIND_APP_DEFINED / KIND_AI_CORRECTION = 6), giving them the same accent
colour as auto-corrections.
2. getStyledSuggestedWord(): Adds an italic StyleSpan for AI suggestions so
users can visually distinguish them from regular word predictions.
Both method signatures and bodies verified against HeliBoard main (Apr 2025).
