Reconcile v0.10.0 external closure

[xeonvs]

Scope

Complete the already-published v0.10.0 lifecycle with a strict, documentation-only
no-release reconciliation. No package/runtime source, stable/dev marker, release
metadata, tag, distribution, registry publication, provenance, attestation, receipt,
or GitHub Release asset is changed.

Verified delivery

• Release PR: Release v0.10.0 #185
• Protected merge: f33674ebe88eab10406123299e8a9c8728171781
• Successful idempotent recovery: workflow 34348030036
• Immutable release: v0.10.0
• Authorized issue set: [OCR compatibility] Qualify v1.11.6 #181, Standalone local review provider, shared summary and truthful debug diagnostics #182; each has one GitHub Actions-owned receipt and is closed.
• Milestone v0.10.0 is closed with zero open issues.

The first release workflow, 34347350040, passed its build, registry, provenance, attestation and supported-Python gates, but GitHub returned an Internal Server Error while accepting the new tag; no tag, Release, receipt, or issue receipt had been created. The recovery dispatch reused the exact authorization tuple and completed idempotently.

Changes

1. Advance .release-reconciled-version from 0.9.1 to 0.10.0.
2. Replace the pending v0.10.0 archive state with concise, independently-read-back facts.
3. Update the archive index from stable-delivery handoff to completed external reconciliation.
4. Document and test the rule that release PRs list tracked issues only in non-closing prose: the Release workflow is their sole post-receipt closure owner.
5. Correct the closed Release v0.10.0 #185 PR body to remove the accidental closing phrase that caused [OCR compatibility] Qualify v1.11.6 #181's premature merge-time closure; this does not mutate any published artifact.

Local validation and self-review

• uv run pytest tests/test_operations_docs.py -q: 31 passed
• uv run ruff format --check tests/test_operations_docs.py: passed
• uv run ruff check tests/test_operations_docs.py: passed
• git diff --check origin/main...HEAD: passed
• scripts/gitleaks.sh f33674ebe88eab10406123299e8a9c8728171781 HEAD: passed
• Full scope review confirms exactly five files, all closure documentation/marker/test surfaces.

No OCR or Codex Security rerun is appropriate for this no-release closure; the sole
authorized final OCR review was already completed for the feature range, while hosted
CI will validate this exact documentation head.
