feat: put the signature cache behind a feature flag (enabled by default)#481
Merged
Conversation
…es and suppress implicit dep features Use `dep:` prefix for optional dependencies so the `cached`, `lazy_static`, and `parking_lot` crate names are not leaked as public features. Fix cfg gates that were relying on the implicit `cached` feature to now use the canonical `signature_cache` feature name. Add a regression test that verifies the cached path is taken when the feature is enabled. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Currently they can't because the
