Complete terminal rewrite for full TUI compatibility
- Alternate screen buffer (smcup/rmcup) for mc, vim, htop, less
- 256-color and truecolor rendering (dynamic tag creation)
- Reverse video and strikethrough attributes
- write_process_input bridge (DA/DSR responses to SSH)
- DECCKM application cursor keys for arrow navigation
- Alt+key combinations (mc panels, readline word nav)
- Shift+Arrow / Ctrl+Arrow with xterm modifier encoding
- Shift+Tab (backtab) for reverse completion
- Bracketed paste mode for clean multi-line paste
- Mouse tracking (basic, button, any-event, SGR extended)
- Incremental UTF-8 decoder (handles split multi-byte)
- Cursor hidden state (DECTCEM) respected
- pyte dirty set for optimized rendering
- Numpad key support
- Professional copy/paste UX:
- Ctrl+C always sends SIGINT
- Ctrl+Shift+C/V for copy/paste
- Right-click context menu with Copy/Paste/Select All
- Double-click to select word
- Smooth mousewheel scroll (3 lines in alt screen)
- Thread-safe session management (all state on main thread)
- Resize debounce reduced to 100ms
- Send errors trigger disconnect notification
