release-v1.0.12 - Native Termux Terminal Emulator

What's Changed in v1.0.12

🖥️ Native Termux Terminal Engine Integration

• Embedded Termux Terminal Emulator: Replaced the plain-text transcript with a fully native Android terminal emulator view (opencode-terminal local Expo Module) powered by Termux's battle-tested terminal engine (com.termux.terminal and com.termux.view).
• Full VT100 / VT220 / xterm Compatibility: Full support for ANSI escape codes, 256 colors / 24-bit true color, alternative screen buffers (for full-screen interactive TUIs like vim, nano, htop, fzf), and hardware-accelerated canvas text rendering.
• Remote WebSocket PTY Streaming: Custom TerminalSession engineered for remote opencode server streaming without requiring local JNI subprocess forks.
• Dynamic Terminal Sizing: View layout and font size changes automatically calculate character grid dimensions and notify the backend PTY session to resize.
• Theme Matching: Seamless color palette integration matching HeroUI / Uniwind dark and light modes (background, foreground, cursor, and 16 ANSI colors).

⌨️ Mobile Input & Usability Improvements

• Interactive Keyboard Input: Enabled native touch focus and proper Android IME text attributes (TYPE_CLASS_TEXT) so virtual keyboards (Gboard, Samsung, MIUI) open and dispatch keystrokes reliably.
• Display Density Font Scaling: Fixed raw pixel scaling by applying Android scaledDensity metrics, ensuring sharp and readable text across various device DPIs.
• Pinch-to-Zoom Scaling: Zoom terminal font size dynamically on screen using two-finger pinch gestures.
• Keyboard Toolbar & Command Bar:
  • Added a dedicated Keyboard toggle button to easily summon the software keyboard.
  • Added an inline command input bar with a Send button.
  • Added quick modifier buttons for Tab, Ctrl+C, Ctrl+D, Esc, arrow keys (↑, ↓, ←, →), Enter, and Clear.

📦 Build & Release

• Added standalone arm64-v8a release APK with the new native module.
