- verify-skills: the best-effort `plugin validate` hand-off now also requires
the EXACT pinned CLI. `local:gate` runs `validate` before the pinned
`verify:skills:cli` step, so a newer local CLI could reject skills that CI's
pinned validator accepts — and the gate would exit there, never reaching the
reproducible check. One schema everywhere, or none.
- Dropped `PLUGIN_VALIDATE_MIN_VERSION`: with both validators on the exact pin
it was read only by its own test, and a constant nothing enforces is a claim
nothing enforces. Its test now pins what actually matters — that equality is
distinguishable from newer as well as older.
- The CI step's comment described the old floor behavior.
- issue-create: the duplicate check searched only open issues, so a completed or
rejected match was invisible to a procedure that says never to duplicate.
