Pre-commit Pytest Hook Implementation Summary

Here’s the summary:

WHAT WE DID: Added pytest as a pre-commit hook so tests run on every git commit (~8s, 1860 tests, all pass).

PARALLEL TESTS: Tested pytest-xdist with -n 2, -n 4, -n auto. No improvement — individual tests are too fast (~4ms each) for parallelism overhead to pay off. Also got Bad file descriptor errors from I/O tests conflicting with process forking.

VERDICT: Keep sequential. Parallel would only help if individual tests were 100ms+ (API calls, model loading). Added pytest-xdist to dev deps anyway for future use with slower suites.

FILES CHANGED:

.pre-commit-config.yaml — added unit-tests local hook
pyproject.toml — added [dependency-groups] with pytest, pytest-xdist, coverage
