Function isLowValueFile

src/db/queries.ts:37–54

* Files that should not be candidates for "dominant file" detection: test/spec * files and tool-generated files. Generated files (`*.pb.go`, `*.pulsar.go`, * mock outputs, …) often have huge in-file edge counts that dwarf the real * source — etcd's `rpc.pb.go` has 4× the in-file edges of `server.

(filePath: string, generated?: ReadonlySet<string>)

 * to catch it (#1500).
