Task prefill reliability · Seedance references · workspace ordering

Task creation and prompt handoff
- Fixed cases where prompts opened from tool pages or task links could disappear before the composer was ready.
- Fixed same-page task links so a new prefilled prompt refreshes correctly instead of keeping the previous draft.
- Improved first-frame draft handling so prefilled task text appears reliably even during fast route changes.
Seedance video generation
- Fixed reference-mode requests that could be rejected by the provider when image references were passed through the generation flow.
Spaces
- Fixed duplicate workspace ranks that could make space reordering fail when owned and shared spaces appeared together.
Session cleanup
- Improved cleared conversation cleanup so archived runtime transcripts do not leak back into future restored sessions.
