perf: anonymize files in parallel with a process pool#23

Each file gets its own TraceAnonymizer, so files are fully independent and can be processed concurrently. Directory anonymization now fans out over a ProcessPoolExecutor sized to the machine's CPU count, falling back to the sequential path for small batches where process startup would cost more than it saves.

Directory anonymization processed files strictly sequentially, but each file already gets its own
TraceAnonymizerinstance (replacement maps are per-trace by design), so files are fully independent.This fans the per-file work out over a
ProcessPoolExecutorsized toos.cpu_count()(falling back to 1 when unavailable — no hardware assumptions). Batches under 8 files keep the sequential path, since process startup would cost more than it saves. Report ordering, per-file scoping, and output are unchanged;executor.mappreserves the sorted file order.Testing
