- nodes/__init__.py: fix [PrismAudio] leftover label in error print
- selva_feature_extractor: hash beginning, middle and end of video tensor
instead of just first 1MB, avoiding collisions on videos with same opening frames
- selva_sampler: derive SequenceConfig from model template via dataclasses.replace
instead of hardcoding sampling_rate/spectrogram_frame_rate per mode

Users can now wire the prompt output directly to SelvaSampler's prompt input,
making the data flow explicit instead of relying on the implicit features fallback.

SelvaFeatureExtractor now stores the prompt in SELVA_FEATURES (both in the
returned dict and the .npz cache). SelvaSampler's prompt is now optional —
when left empty it falls back to the prompt stored in features. A non-empty
override can still be passed when CLIP text should differ from the sync text.

- selva_feature_extractor: cache hash now includes resolved duration;
same video + different duration override no longer returns stale features
- selva_sampler: MPS-safe noise generation (torch.Generator on CPU then
move to device, same pattern as PrismAudioSampler)

CLIP frames at 8fps→384px (normalize inside FeaturesUtils).
Sync frames at 25fps→224px, normalized to [-1,1] externally.
T5 text encoded via FeaturesUtils, sup tokens prepended, then text-conditioned
sync features extracted via TextSynch.encode_video_with_sync(). Results cached
as .npz keyed by hash(frames[:1MB] + prompt + fps + variant).
