Add v0.5.0: CCGS Skill Testing Framework, skill-improve, 4 new skills, director gate path fixes

- Add CCGS Skill Testing Framework: self-contained QA layer with 72 skill specs,
  49 agent specs, catalog.yaml, quality-rubric.md, templates, README, CLAUDE.md
- Add /skill-improve: test-fix-retest loop covering static + category checks
- Add 4 missing skills: /art-bible, /asset-spec, /day-one-patch, /security-audit
- Add /skill-test category mode (Phase 2D) with quality rubric evaluation
- Extend /skill-test audit to cover agent specs alongside skill specs
- Update all skill-test and skill-improve path refs to CCGS Skill Testing Framework/
- Remove stale tests/skills/ directory (superseded by CCGS Skill Testing Framework)
- Add director gate intensity modes (full/lean/solo) to gate-check and related skills
