feat(2149,2150): add project skills awareness to 9 GSD agents (#2152)

- gsd-debugger: add Project skills block after required_reading
- gsd-integration-checker, gsd-security-auditor, gsd-nyquist-auditor,
  gsd-codebase-mapper, gsd-roadmapper, gsd-eval-auditor, gsd-intel-updater,
  gsd-doc-writer: add Project skills block at context-load step
- Add context budget note to 8 quality/audit agents
- gsd-doc-writer: add security note for user-supplied doc_assignment content
- Add tests/agent-skills-awareness.test.cjs validation suite
