* feat: enhance feedback form with image upload, user/project context, and scene graph
- Add invisible drag-and-drop zone that reveals on hover+drag with dashed border overlay
- Multi-image upload (max 5, max 5MB each) to Supabase Storage feedback-images bucket
- Subtle attach button + thumbnail previews with remove on hover
- Auto-capture authenticated user email/name from Better Auth session
- Pass projectId from editor context
- Snapshot scene graph (nodes + rootNodeIds) on submit
- DB migration adds user_email, user_name, project_id, images (jsonb), scene_graph (jsonb) columns
- Storage bucket + RLS policies for public read / service role write
* refactor: use existing user_id FK instead of denormalized email/name columns
Removed user_email and user_name — the user_id already links to the users table.
Simpler schema, no data duplication.
* fix: guard against undefined in removeImage
* refactor: direct Supabase Storage upload via signed URLs
Bypass Vercel's 4.5MB serverless body-size limit by uploading images
directly from the client to Supabase Storage.
- New createImageUploadUrls server action generates signed upload URLs
- Client PUTs files directly to Supabase (no bytes through Vercel)
- submitFeedback now receives only image paths, not FormData with files
- No migration changes needed (existing RLS policies support signed URLs)
* fix: remove relative class that broke dialog centering
twMerge was replacing the Dialog's fixed positioning with relative,
pushing the dialog to the bottom of the viewport.
