Summary

Release commit for v11.83.1, produced by scripts/release.sh (version touchpoints and CHANGELOG section; run as a dry run on this branch so the commit goes through a PR, then tagged on the merge commit). It covers #209-#219.

• Version 11.83.1 in pyproject.toml, package.json, package-lock.json, the OpenCode plugin, the Claude plugin and marketplace manifests, b12_mcp_server.py, b12_health.py and the installer banner
• CHANGELOG: the [Unreleased] block is replaced by the curated [v11.83.1] section (the splice fixed in fix(release): replace the [Unreleased] block and fill changelog gaps #219)
• README "Changelog (recent)": v11.83.1 entry with three highlights

Test plan

• release.sh touchpoint verification and scripts/check_package_versions.py pass (11.83.1)
• scripts/tests/test_package_version_sync.py and test_version_doc_drift.py pass

Anti-Claude trailer check

• No Co-Authored-By trailers
• No generated-with footer
