test_ohlcv_fixtures

Polars-free validation of the OHLCV golden fixtures.

Recomputes bars from the prepared-trades fixture with pure Python and compares against the exported bars, so hardware-facing tests can rely on these files without a polars dependency. Fixtures are generated by python -m dau_polars.ohlcv_fixtures (see dau-docs-private/OHLCV_BARS.md).
