docs(ledger): record open-PR merge sweep outcomes

[BigSimmo]

Summary

• Records the authorized newest→oldest open-PR merge sweep in docs/branch-review-ledger.md.
• Includes per-PR merge/skip outcomes and superseding rows for fix: Implement audit design fixes and fallback improvements #1351 (merged) and chore: execute audit remediation fixes and RAG governance #1352 (closed as superseded by Harden clinical-notes trust gating and finish audit remediations #1305).
• Docs/ledger only — no product or RAG behaviour change.

Verification

• npm run ledger:append for superseding fix: Implement audit design fixes and fallback improvements #1351/chore: execute audit remediation fixes and RAG governance #1352 rows
• Branch synced with current main (includes fix: Implement audit design fixes and fallback improvements #1351)
• Verification not run: runtime gates — ledger-only change

Risk and rollout

• Risk: none to runtime
• Rollback: revert the ledger rows
• Provider or production effects: None

RAG impact: no retrieval behaviour change — ledger documentation only

Summary by CodeRabbit

• Documentation
  • Updated the branch review ledger with current merge, closure, and ownership handoff outcomes.
  • Added status details for superseded changes, required checks, build validation, and merge conflicts.
