filtering, cost/UX improvements
- Replace interval polling with signal-only updates for both workspace
panels and iterative editor (one-time initial check
as fallback)
- Only include reference images when user explicitly
@mentions a
character in the prompt (previously fell back to all
references)
- Return actual generation cost from server instead of
static estimates
- Add "Reset to original" button to revert to initial
source image
- Support generating multiple images (1-4) per request
with pick grid
- Fix across all endpoints: createPanel, enhancePanel,
iterateGenerate,
smartCreateChapter, bulkCreatePanels
