Ethanfel 707ccb463e perf: replace MP4 encode/decode with lossless .npy frame transfer 
Saves frames as uint8 .npy instead of H.264 MP4, eliminating the
lossy codec roundtrip. extract_features.py loads .npy directly and
skips decord when given a numpy file. Passes --source_fps for
correct temporal sampling.

Ethanfel 20fb766ad2 fix: cast tensors to float32 before numpy() in feature save 
T5-Gemma outputs BFloat16 which numpy does not support.
Cast all feature tensors with .float() before .numpy().

Ethanfel 829f398ed0 feat: verbose step-by-step logging in feature extraction 
- extract_features.py: 6 numbered steps with shapes, fps, frame counts
- feature_extractor.py: stream subprocess output live (capture_output=False)

Ethanfel 878025450a feat: add data_utils package with FeaturesUtils implementation 
Creates data_utils/v2a_utils/feature_utils_288.py with FeaturesUtils:
- T5-Gemma text encoding via transformers
- VideoPrism video encoding via JAX videoprism package
- Synchformer visual encoder loading from checkpoint

Also fixes extract_features.py to add plugin root to sys.path so
data_utils is importable in the subprocess venv.
