Doc drift: CONTRIBUTING's develop branch doesn't exist; ISO 42001 SoA says 42 controls, lists 36 #222

Two statements that don't match the repository:

• CONTRIBUTING.md (around lines 48–61) describes claude/<topic> → develop → main and says "PRs target develop". But there is no develop branch on origin, and recent PRs (build(deps): bump urllib3 and pyjwt for security advisories #209, fix(eval): tuning-scope fingerprint ignores docstrings #210, build(deps): bump huggingface-hub to 2.2.0 and tokenizers to 0.23.3, and keep the CDK pins out of the uv group #212) merged straight into main. Fix one of the two:
  • update CONTRIBUTING to describe the trunk-on-main flow; or
  • create develop and retarget PRs to it.
• docs/audits/iso42001-soa.md: the header says "the 42 Annex A controls", but the tables list 36 (35 applicable, 1 N/A). Either list the missing controls or correct the count. docs/case-study.md in fix(retrieve): scope retrieval to the answer language (#168); readiness note and case study #220 cites 36.
