The regression row grepped only the four current ceremony names, so a
future enumeration under new names stayed green. Widen the pattern to
scope:[a-z0-9] — any concrete label name, in any shape, re-reds the row,
while doctrine's bare `scope:` and wildcard scope:* stay allowed (#104).

The mirror is byte-identical in every governed repo, so the four-row
enumeration was true at home and false in rig, box, cast and incubator —
14 of 16 vendored rows lied. The section keeps its doctrine and points at
the two places true wherever the reader stands; ceremony's own set is now
a pointer sentence in CONTRIBUTING, and a labels.test.sh row (red on main,
4 hits) keeps enumeration from returning.
