docs: refresh published reference docs against current code

- CLAUDE.md + README.md: RAG engine is hybrid retrieval, not HyDE (retired)
- usage.md: org chart + agent-IDs table now show all 22 agents (adds
  secretary-1 + pr-reviewer-1); task-lifecycle diagram adds awaiting_pm_review
  and the awaiting_ceo_approval escalation
- deployment.md: architecture diagram + data-persistence table include ollama,
  panel, nginx, workspaces, and logs
- docs/initiatives + docs/self READMEs: access lists match middleware_docs.py
- CLAUDE.md blueprint pointer no longer references the gitignored docs/internal tree
