API: add Signature support and smarter client caching (piotrtomiak6894935)

The native-preview API now exposes Signature objects end-to-end and adds a snapshot-aware object registry to cache symbols, types, signatures, and type lists on the client side. This reduces redundant round trips and makes async/sync API behavior more consistent.

Fix redundant undefined wrapping in declaration emit (jakebailey462a1a4)

Declaration emit no longer adds duplicate | undefined wrappers in optional-parameter cases. The fix tightens the node builder and pseudo-type conversion logic so emitted .d.ts output matches the underlying type more accurately.

Fix auto-import crash in alias resolver (dd6bceb)

Auto-import now avoids panicking when IsSourceFileDefaultLibrary is queried on the alias resolver. A regression test was added to ensure diagnostic collection during export extraction can tolerate a file with type errors.
