docs(oath): correct stale Executor framing after swedsl#27 closed

swedsl#27 (var-go strategic-fit ADR) closed 2026-07-18 and killed the
Executor/Reviewer path entirely — var-go is gate-only by design, each
consuming repo supplies its own candidate. The real blocker for
enforcement here is swedsl/oath's non-importable module path
(swedsl#35), not a nonexistent Executor. Corrects PROJECT.md,
INCEPTION-OATH.md, and the cd.yml comment to match.
