- Fix workflow frontmatter: remove 'name:' field (Antigravity uses
filename as command name), add numbered steps format
- Add 6 new workflows: /debug, /tdd, /review, /verify, /finish-branch,
/worktree — now 9 slash commands total
- Add workflow frontmatter validation to validate command
- Update check-pack.mjs for new workflow files
