♻️ refactor(skills): update playbook.py and tests for thirdparty/ layout

- install_skills_action: collect skills from both codex/skills/ (own) and
  codex/skills/thirdparty/ (thirdparty); mode=all installs both, mode=list
  searches both; log [thirdparty] tag for third-party installs
- Update test_thirdparty_skills_pipeline: fix source_list path assertion
- Update SKILLS.md: document thirdparty/ subdirectory structure
