• new AI terminal toolchain. 5 new tools: start_command (fire-and-forget), capture_terminal (read screen), collect_output (passive wait), send_terminal_key (interactive input), interrupt_command (cancel). execute_command gains configurable timeout and output truncation.

• new AI sidebar search. Highlight matches, navigate matches (Enter / Shift+Enter), match count, auto-scroll to active match.
• bugfix Fixed text search menu opening search bar in all terminal windows simultaneously. Event now targets the current panel.
