Add value source card crosslinks and fix scene initial value bias

- Audio value source cards link to the referenced audio source
- Adaptive scene cards link to the referenced picture source
- Fix SceneValueStream starting at 0.5 regardless of actual scene;
  first frame now skips smoothing to avoid artificial bias
- Add crosslinks guidance to CLAUDE.md card appearance section

+- **Crosslinks**: When a card references another entity (audio source, picture source, capture template, PP template, etc.), make the property badge a clickable link using the `stream-card-link` CSS class and an `onclick` handler calling `navigateToCard(tab, subTab, sectionKey, cardAttr, cardValue)`. Only add the link when the referenced entity is found (to avoid broken navigation). Example: `<span class="stream-card-prop stream-card-link" onclick="event.stopPropagation(); navigateToCard('streams','audio','audio-multi','data-id','${id}')">🎵 Name</span>`
