Cancel Ralph-Loop++ Session

Cancel any active optimization session and clean up resources.

Steps

1. Check for active session by reading .claude/ralph-plus.local.md

3. If active session found:
   • Kill any running worker processes
   • Delete all worktrees created for this session
   • Mark the session as cancelled in the state file
   • Report what was cleaned up

Cleanup Process

# Find and remove worktrees
git worktree list | grep "ralph-plus" | awk '{print $1}' | xargs -I {} git worktree remove {} --force 2>/dev/null || true

# Clean up branches
git branch | grep "ralph-plus/" | xargs -I {} git branch -D {} 2>/dev/null || true
