feat(tools): add interactive_bash tool for tmux session management

Add a new tool for managing tmux sessions with automatic tracking and cleanup:

- interactive_bash tool: Accepts tmux commands via tmux_command parameter
- Session tracking hook: Tracks omo-* prefixed tmux sessions per OpenCode session
- System reminder: Appends active session list after create/delete operations
- Auto cleanup: Kills all tracked tmux sessions on OpenCode session deletion
- Output truncation: Registered in TRUNCATABLE_TOOLS for long capture-pane outputs
