issue_comment triggers had two problems: Gitea did not reliably fire
them, and the refs/pull/N/head checkout was fragile. Commit-message
keywords are simpler and guaranteed to work on any push event.
Trigger keywords (add anywhere in the commit message):
/test-cgal → CGAL test suite (277 tests, LOW_MEMORY_BUILD)
/quality-gates → license/codespell/shellcheck/cgal-conventions
/docs → Doxygen build + warning summary
/links → Markdown internal link check
test-fast still runs on every push (no keyword needed).
All `issue_comment` event handlers and `refs/pull/N/head` checkouts
removed from all three workflow files. review/** added to push branch
filters so this PR branch triggers normally.
CLAUDE.md CI table updated.
