	2	* Block J7 — Closing keywords.
	3	*
	4	* Parses PR body + commit messages for GitHub-style "closes #N" phrases and
	5	* returns the de-duplicated set of issue numbers that should auto-close when
	6	* the PR merges. Pure; zero IO.
	7	*
	8	* Accepted verbs (case-insensitive):
	9	* close(s\|d), fix(es\|ed), resolve(s\|d)
	10	*
	11	* Optional punctuation between the verb and the issue ref ("Fixes: #12",
	12	* "Closes #12.") is tolerated. Refs must be bare `#<number>` — cross-repo
	13	* refs like `owner/repo#12` are intentionally ignored for v1 because
	14	* cross-repo auto-close requires authorisation we don't track yet.
