predicates.ts: Replace defaultPredicatesRegistered boolean guard with
sentinel predicate check inside the registry. registerDefaultPredicates()
is now always safe to call — no module-scope flag that can drift out
of sync with the actual registry state. clearPredicateRegistry() no
longer needs to manually reset a flag.
extraction.ts:
- Replace compatibilityWarningEmitted process-singleton boolean with
WeakSet<ImhotepUi> (warnedUis). Each ImhotepUi instance now gets its
own compatibility warning, fixing the bug where two pages would share
a single warning gate.
- Export resetExtractionPathStats() for test isolation of fast-path
and CDP fallback counters.
598 SDK + 3 conformance + 57 E2E = 658 tests pass.
