- Add mbp10_data_dir and trades_data_dir to smoketest TOML profile
- Fix data_loading path resolution: resolve relative paths against
workspace root via CARGO_MANIFEST_DIR (CWD is crates/ml during tests)
- Add buffer_size floor of 1024 in hyperopt adapter (GPU PER minimum)
- Regenerated fxcache with full OFI features (MBP-10 + trades)
All tests now consistently hit fxcache with OFI=true.
