The `# mcrf:` stamp recorded verified=<version>@<commit>, so every commit rewrote
the hash in all 130 snippet headers -- a guaranteed 130-file diff carrying no signal
git history doesn't already have, and one `--check` ignores anyway. The version alone
is stable within a dev cycle ("0.2.8-dev") and becomes the release marker at a tag
("0.2.9"), which is the whole point of the field: freezing a version into the docs
site's history, not pinning a commit.
verified is now version-only. The stamper is idempotent again: a second run on a
clean tree changes zero files. This commit is the one-time normalization that strips
the @hash suffix from the existing headers.
Found while cleaning up after a make release-docs run left all 130 snippets dirty
with nothing but hash churn.
