Subject: [PATCH] fix(round): labeler.yml header tells the truth; labels-scope
 maps to scope:labels
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The mapping header still described actions/labeler@v5 + sync-labels —
the exact mechanism this PR removed; it now describes labels-scope's
base-ref read and additive POST, keeping the #128 incident. The
scope:labels row gains actions/labels-scope/** and its test, and two
fixtures derive against the real mapping so the coverage is tested, not
just present. The reconcile job comment names labels-scope instead of
labeler (grok nit 3).
