fix(licence): clear scaffold-placeholder leak (isolated; dirty repo)

#3 isolated commit. ONLY placeholder SPDX lines staged; repo's other
uncommitted WIP deliberately left untouched/unstaged. PLMP/PMLP +
doubled = scaffold artifacts (LICENCE-POLICY.adoc A5), NOT relicensing.
Diff-shape asserted (SPDX-only). Refs standards LICENCE-POLICY.adoc A5.
