CLM v1.8.2

Changed

• Releases can now be cut merge-driven, not only by an explicit tag. The
  release workflow also triggers on a master push that introduces a
  Bump version … commit (e.g. merging a bump PR with a merge commit): it
  gates on CI, then creates the vX.Y.Z tag and publishes. Pushing a vX.Y.Z
  tag directly still works as a fallback. Every external action (tag, PyPI
  upload, GitHub Release) is idempotent, so a re-run never double-publishes. See
  docs/developer-guide/releasing.md.
