fix(licence): clear scaffold-placeholder leak (Tranche 1)

#3 Tranche 1. PLMP/PMLP-1.0-or-later sentinel + PMPL-1.0-or-later-or-later
are scaffold-substituter artifacts (LICENCE-POLICY.adoc A5), NOT
relicensing. Substituted to this repo's correct id PMPL-1.0-or-later.
Diff = SPDX identifier lines ONLY (diff-shape asserted; auto-revert on
any anomaly). No 3c-sensitive file touched.
Refs hyperpolymath/standards LICENCE-POLICY.adoc A5.
