Subject: [PATCH] ci: reject PRs that reference the assistant by name in
 title/body/commits

Server-side counterpart to the global commit-msg hook (which blocks the same word
locally, but can be bypassed with --no-verify or via GitHub UI edits). Checks only
message text, never file contents.

+# Server-side counterpart to the global commit-msg hook: rejects a PR whose
+# title, body, or commit messages mention "claude" (any case). Catches commits
+# pushed with --no-verify and edits made in the GitHub UI. Only message text is
+# checked — never file contents, since the code legitimately references claude.
