feat(kb): CRM association proof via oo, fix ssh-tunnel self-ref + oo creds

- bin/facts/crm: prove person<->company/company<->project against ooCRM
  x corpus SoT (knowledge-mesh-seed.yaml), write 78 facts (root=facts)
- tools/crmfacts.py + test_crm_facts.py: parser under unit tests (26 pass)
- docs/crm-associations-proof.md: provable graph, mistakes, fixes
- oo merge 759->763 resolves duplicate GoldenRatio.Exchange legal entity
- bin/db/ssh-tunnel: "$0" self-check + accept-new/BatchMode ssh flags
- AGENTS.md: document bin/facts/crm
