- Fix race condition where watch endpoint couldn't find active generation
because generate hadn't registered yet. Workshop page now triggers
/generate before connecting to /watch.
- Add polling fallback in watch endpoint (up to 3s) for edge cases where
generate route is still starting up.
- Add progress panel for regeneration - was missing because the panel
was only shown when !hasDraft.
- Add comprehensive logging throughout generation pipeline for debugging.
- Improve generation registry with subscriber management and accumulated
reasoning text for reconnection support.
