5 bite-sized tasks: SKILL.md measurement half (L1-L2) + decision half
(L3-L4/verdict), gsc_signal_delta.py helper with TDD tests, marketplace
registration + spec-layout reconcile, and a genesis-case smoke test that
asserts the JHR "호텔" claim resolves to ARTIFACT.

New conductor skill that adjudicates whether a claimed SERP/Knowledge-Graph
movement for a (term, entity) pair is real, misattributed, an artifact, or
unprovable. Stateless, on-demand; delegates measurement to seo-serp-analysis,
seo-position-tracking, and seo-knowledge-graph. Genesis: JHR "호텔 16→3"
SEMrush claim refuted via GSC/GA4/live-SERP cross-check.
