The component was only fetching as many lines as could fit in its container,
which could miss important context. Now it fetches at least one full terminal
screen worth of lines (stats.rows) to ensure we capture the complete visible
terminal state.
Also improved rendering to show the bottom portion when we have more lines
than can fit in the display area.

The binary encoding was using 16-bit unsigned integers which failed when:
- Terminal has many rows (>65k)
- Cursor is above the viewport (negative relative position)
Changes:
- Upgrade to version 2 of the binary format
- Use 32-bit integers for dimensions and positions
- Use signed integers for viewport/cursor positions
- Update header size from 16 to 32 bytes
- Update documentation to reflect new format
This fixes the issue where cursorY could be negative when the cursor
is above the visible viewport (e.g., cursorY=0, viewportY=46 results
in relative cursorY=-46).

Replace terminal.ts in session-card with new buffer-based component that:
- Fetches terminal buffer snapshots via JSON API
- Polls every second only when content changes (checks lastModified)
- Automatically calculates lines needed based on container height
- Reuses terminal rendering styles and logic
Changes:
- Create terminal-renderer.ts with shared rendering logic for both components
- Add vibe-terminal-buffer component that works with buffer API
- Update session-card to use vibe-terminal-buffer instead of vibe-terminal
- Add terminal-line CSS for proper styling
- Fix color handling in terminal-manager (-1 means default color)
- Add debug logging to help diagnose rendering issues
The new approach is more efficient - no cast file parsing, just direct
buffer snapshots from the server.

Major architectural change: replaced tail -f streaming with direct file watching
and server-side terminal state management for better performance and efficiency.
Key changes:
- Add StreamWatcher class using fs.watch() instead of tail -f process
- Benchmarks showed fs.watch() is faster and more efficient
- Handles multiple SSE clients per session without duplicate processes
- Streams existing content then watches for new data
- Add TerminalManager class for server-side xterm.js instances
- Maintains headless terminal state per session
- Watches stream files and feeds data into terminals
- Provides binary buffer snapshots on demand
- Add new /api/sessions/{id}/buffer endpoint
- Returns efficient binary terminal buffer snapshots
- Supports viewportY and lines parameters for partial updates
- Uses run-length encoding for compression
- Create comprehensive binary format documentation (snapshot-format.md)
- 16-byte header with dimensions and cursor position
- Variable-length cell encoding with UTF-8 and RGB support
- ~75% size reduction compared to JSON
- Fix cmdline.join() error with defensive programming
- Handle cases where cmdline might not be an array
This enables session-list.ts to efficiently show terminal states without
overwhelming client/server resources.

The terminal component was aggressively preventing default on ALL keyboard events, blocking important browser shortcuts like F12 (DevTools), Ctrl+C/Ctrl+V (copy/paste), and Ctrl+F (find).
Updated the keyboard handler to:
- Allow F12 and Ctrl+Shift+I/Cmd+Alt+I for DevTools
- Allow common browser shortcuts like Ctrl+A, Ctrl+F, Ctrl+R, etc.
- Allow Alt+Tab and Cmd+Tab for window switching
- Only preventDefault on keys that are actually handled by the terminal
This preserves terminal functionality while restoring essential browser shortcuts.

The server now waits for tty-fwd to fully register the session before
returning the response. This prevents the frontend from querying for a
session that doesn't exist yet in the session list.
Also removed the problematic frontend fallback that would select the
"most recent" session when the exact ID wasn't found, which was causing
it to open the previous session.
