Add flick: Ralph cleanup skill and script

[saiyajosh]

Motivation

Found myself needing to search for and cleanup these files (admittedly I just wanted to not archive, and just blow these intermediary files away), so I made this little helper.

Thought it might be useful for others, so sharing.

Summary

• Adds a /flick skill and flick.sh script to find and delete Ralph intermediary files (prd.json, progress.txt) after a completed run.
• Updates ralph.sh to display a cleanup tip on successful completion.

❯ ./ralph.sh --tool claude
Starting Ralph - Tool: claude - Max iterations: 10

===============================================================
  Ralph Iteration 1 of 10 (claude)
===============================================================
All stories have `passes: true`.

<promise>COMPLETE</promise>

Ralph completed all tasks!
Completed at iteration 1 of 10

Tip: clean up Ralph's intermediary files when you're ready:
  Via your AI coding tool : /flick
  Via script (from project): path/to/ralph/flick.sh
  
  ❯ ./flick.sh

        "One line added to README.md (e.g., a badge, a note, or a minor clarification)",

        "Commit is clean and repo remains in a healthy state"
      ],

Delete these files? (y/n)

Key Changes

skills/flick/SKILL.md — Claude Code skill

• Defines the /flick skill so users can trigger cleanup directly from their AI coding tool
• Supports --nuke, --all, "nuke it", "delete everything", and "delete all" as force-delete triggers
• Covers the same search locations as the shell script

flick.sh — cleanup script

• Alternative to ai-native skill (more direct, less token usage, if developer prefers)
• Searches known Ralph file locations (project root, .agents/ralph, .claude/ralph, and user-level equivalents)
• Shows a preview of prd.json (first 15 lines) before prompting for deletion
• Supports --nuke and --all flags to skip confirmation prompts and delete all found files immediately

ralph.sh — completion tip

• Prints a helpful tip on successful run completion pointing users to both the /flick skill and flick.sh script
