createJournalEntry now cancels the draft with a CAS guard (status='draft')
if commitEntry throws, so callers don't leave undeletable stuck drafts when
the commit RPC rejects (balance trigger, period lock, overload ambiguity).
Also adds a PR-triggered GitHub Actions workflow that runs Claude against
the diff using the swedish-* skills as authoritative references and posts
advisory compliance feedback as a PR comment.
