Pull request overview
This PR parallelizes the vesskel run CLI batch workflow by introducing a multiprocessing worker module and a --jobs/-j flag, while also adding a regression test to ensure shell completions exit without importing heavy modules.
Changes:
- Add
--jobs/-jto control parallel worker count for batch runs (with a serial fallback). - Factor batch I/O + per-file processing into a new
vesskel/_batch.pyworker module forProcessPoolExecutor. - Add a test to ensure CLI shell completions do not import heavy modules (numpy/PIL/pipeline).
