Create Worktree: Creates a new git worktree with a feature branch and opens it in a new iTerm2 tab
Close Worktree: Safely closes worktrees after verifying they're clean and pushed
Open Worktree: Opens an existing worktree in a new iTerm2 tab (with force option to override if already open)

Active Worktrees: Lists all git worktrees and shows which iTerm2 tabs they're running in
Switch to Worktree: Quickly switch to a worktree's iTerm2 tab by name or specific tab ID

Dynamic Discovery: No metadata files - finds tabs by analyzing their working directories in real-time
Multi-Tab Support: Shows all tabs running the same worktree across different windows
Window Context: Identifies which tabs are in the current window with thisWindow flag
