feat: AI-CLI workflow optimizations

- 200K scrollback, vi-mode copy, copy-on-select
- Ctrl-A S captures pane to ~/logs/, Ctrl-A L toggles live logging
- Status bar shows git branch + working directory
- Pre-built session: code/git/run/logs windows
- Aggressive resize + focus events for multi-device switching
- Toolbar: added Paste (clipboard), Zoom (pane fullscreen), Save (capture)
- All new windows inherit current working directory
- Toolbar split into 2 rows for more buttons without clutter
