🚀 LeanType 4.3.1-beta1

🐛 Fixed

• Samsung & Multi-Profile IME Crash Resolution: Prevented fatal RuntimeException on Samsung devices (such as Galaxy S25 Ultra) and isolated environments (Knox, Secure Folder, Work Profiles, Direct Boot) where system inputMethodList excludes third-party IMEs, by replacing rigid equality checks with direct package matching and resilient PackageManager fallbacks.
• InputConnection IPC Hardening & Memory Leak Prevention: Hardened RichInputConnection against dead-process and remote app IPC crashes, safely closed unclosed dictionary and asset input streams, and eliminated memory leak vectors.
• Synchronous Blacklist Enforcement: Synchronously loads and reloads the blocked words blacklist to eliminate race conditions where blocked words could temporarily appear in suggestions, and resolved deletion persistence issues.
• N-Gram Context Hash Collision Fix: Corrected hash collisions in NgramContext to ensure accurate next-word context lookups across multi-word prediction pipelines.

✨ Added

• Clear Learned Words & User History: Added a dedicated option in Text Correction / Suggestions settings to reset learned words, personalized dictionary history, and session word boost caches.

⚡ Performance

• Draw-Loop IPC Elimination & Zero Key Allocations: Removed Binder IPC queries from active keyboard canvas draw routines, eliminated temporary object allocations per key draw, and optimized gesture trail invalidation for smooth 60fps rendering.

🧹 Maintenance

• Plugin Update Deduplication & Packaging: Consolidated plugin update checks into a centralized PluginUpdateHelper and hardened build scripts for F-Droid reproducibility.
• Resource & Build Hygiene: Pruned orphaned translation strings, removed redundant ProGuard rules, and removed unused legacy split keyboard configuration references (#751).
