Why: an unset S3 client passed through the Store interface is not a nil interface, so uploads panic instead of using the local artifact directory. Evidence: TestIsNil and TestFinishOpenTypedNilS3UsesLocalArtifacts failed before this change and pass after it. The PostgreSQL case skips unless AGENT_PG_TEST_DSN is set. Impact: only an unset blob store falls back; a constructed S3 or local store is unchanged. Refs: internal/blobstore/blobstore.go internal/store/store.go Co-authored-by: Cursor <cursoragent@cursor.com>
