Validate invalid project reference fields (
168e701)
Adds parsing and config-file validation for malformed project reference entries, covering bad or missing path and circular fields. This tightens tsconfig handling so invalid references are reported instead of being silently accepted.
Fix concurrent extraction cache access (
487baf0)
Protects a shared auto-import extraction cache read with a lock to avoid a concurrent map access race during fallback package indexing. The new regression test exercises the race-prone path across many packages to confirm the cache stays safe.
Other misc changes
- Added/updated tsconfig and build error regression tests for invalid project reference fields.
- Expanded auto-import registry test coverage for concurrent fallback handling.
