fix: resolve ESLint errors and update tests for project-name fallback

- Fix 16 ESLint no-unused-vars errors across hook scripts and tests
- Add eslint-disable comment for intentional control-regex in ANSI stripper
- Update session file test to use getSessionIdShort() instead of hardcoded 'default'
  (reflects PR #110's project-name fallback behavior)
- Add marketing/ to .gitignore (local drafts)
- Add skill-create-output.js (terminal output formatter)

All 69 tests now pass. CI should be green.
