fix(kyberforge): address self-audit findings and update lessons

- Reorder skill-audit description to lead with 'Use when...' trigger (P3)
- Add concrete example to 'control calibration' body discipline check (P4)
- Add bats test files to README file tables for both skills
- Fix REPO_ROOT and SCRIPT paths in bats files after tests/ subdirectory removed
- Add three lessons: plugin cache isolation, spec-grounded rubrics, test file placement
