feat(core-eslint): add usecase-must-be-wired conformance rule

Catches manifest use cases that aren't wired through wireUseCase(...) in
bind-production.ts / bind-dev-seed.ts. wireUseCase is the canonical helper
that attaches __instrumented / __captured / __audited brands — skipping
it produces an unbranded binding that assertFeatureConformance would
reject at boot. This rule shifts that detection from ~3s (boot) to <1s
(lint), keeping the layered conformance pattern: TS brands (compile),
ESLint (lint), boot assertion (dev), smoke tests (CI).

CLAUDE.md + conformance-quickref.md updated for the new rule (5 → 6).
