Catch-up

Analyze the current branch's changes to help resume work:

1. •Check if docs/plans/ exists and read any implementation plans related to current work
2. •Find the default branch (try: main, master, development, develop in that order)
3. •Get current branch name
4. •Show summary: git diff --stat <default-branch>...HEAD
5. •Show actual changes: git diff <default-branch>...HEAD
6. •Provide 3-4 line summary combining:
   • •What the plan says (if plan exists)
   • •What's been implemented based on diff
   • •What appears to be left

Keep summary concise - just key status. Don't elaborate unless asked.
