Integrated terminal

A VSCode-style bottom terminal panel, rendered with xterm.js + WebGL for Ghostty/WezTerm-class throughput, backed by a real PTY. Toggle it with **Ctrl+\``** or the command palette ("Toggle Terminal"). It pairs with the AI CLI providers — run claude/codex` / any tool right in the app.

Architecture

xterm.js (WebGL)  ──onData──▶  pty_write
      ▲                         ▲
      │ term.write(bytes)       │  Tauri commands
   base64 decode                │
      │                         ▼
  Channel<PtyEvent> ◀──── pty_spawn (portable-pty: shell in a PTY)
                                 │  pty_resize / pty_kill

• Backend (src-tauri/src/pty/mod.rs): portable-pty (wezterm’s cross-platform PTY). pty_spawn starts the shell, a reader thread streams output base64-encoded over a Tauri Channel (base64 preserves bytes across chunk boundaries); pty_write / pty_resize / pty_kill drive the session. Sessions live in a PtyState map and are dropped on exit/kill.
• Frontend (src/features/terminal/): TerminalView binds one xterm.js instance (fit + WebGL addons) to a PTY session; TerminalPanel is the tabbed bottom dock. PTY wrappers are hand-written in src/lib/tauri/pty.ts (the Channel arg, like the query-stream wrapper).
• Workbench: terminal.toggle command (palette + `Ctrl+``), docked as a fixed bottom panel below modals.

Notes & follow-ups

• Default shell: $SHELL (unix) / %ComSpec% (windows); cwd defaults to the app’s working dir.
• The dock is a fixed overlay for now (low conflict with the in-flight workbench refactor); a resizable, content-pushing split panel is a natural follow-up.
• Persisting open terminals / splitting panes are future enhancements.
