Ethanfel c0b7ccbcee fix: substitute empty_clip_feat for video features when no video present 
Zero features through bias-free Cond_MLP produce near-zero activations,
not the learned null signal the model was trained with. Use empty_clip_feat
(the learned null video embedding) just like empty_sync_feat for sync.
Also improve text_prompt tooltip to encourage detailed CoT descriptions.

Ethanfel 83a7f2787b feat: add debug_zero_video/sync toggles and feature stats logging to sampler 
Allows isolating which feature set causes quality issues:
- debug_zero_video: zero video_features → text+sync only
- debug_zero_sync: zero sync_features → text+video only
Also logs mean/std/shape for all three feature tensors on every run.
