🚀 What's New in v4.0.0

🛠️ Bug Fixes & Major Stability Hardening

• Native JNI Protection: Added isValidDictionary() guards and exception handling around BinaryDictionary JNI calls to prevent C++ native crashes from killing the keyboard process.
• ANR & Thread Freeze Prevention: Added non-blocking timeouts to CountDownLatch.await() in backup/restore, file copy, and secondary dictionary lookup paths.
• Gesture Index Thread Storm Fix: Switched gesture index building to managed KEYBOARD executor pool with atomic state tracking, eliminating CPU spikes and thread proliferation.
• Memory & View Leak Fixes: Cleared static proxy references in PointerTracker.clearOldViewData(), enabled largeHeap, and trimmed memory when UI is hidden to fix OOMs on high-DPI devices.
• PointerTracker & Settings Safety: Fixed NPEs during rapid view switches and made Settings.getValues() null-safe during layout inflation.
• Screenshot Scanner Optimization: Replaced active background ContentObserver with an on-demand check to eliminate background CPU wakeups while typing.
• Regional Dictionary Fallback & Aggregation: Aggregated main and emoji dictionaries across variant and language fallback directories (en-IN -> en) and fixed regional main dictionary variant detection.
• Emoji Dictionary Persistence: Fixed issue where emoji_*.dict files failed to be recognized after downloading, and added preference tracking to prevent dictionary deletion on upgrade.

🤖 AI Enhancements

• Proofread Anti-Answering Guard: Prevented models (Qwen, Llama) from expanding prompts into multi-paragraph answers during proofreading.
• Clean Translation Output: Automatically strips section headers (Translated text:) and trailing reasoning/thinking blocks from translation outputs.

🌟 UI & Keyboard Improvements

• First-Word Prediction Toggle: Added user setting to enable or disable suggestions for the first word in a text field.
• Hardware Keyboard Mode: Added option to show only the toolbar when a physical keyboard is connected.
• Toolbar Key Spacing: Added equal key distribution for unscrollable expanded and dual toolbars.
• Thai Word Segmentation: Preserved Thai word boundaries and segmentation behavior when using text expansion.
