feat: filter empty projects from public gallery (#125)

* feat(community): filter empty projects from public gallery

Add is_empty column to projects table so the public gallery only shows
projects with actual content. Scene graph emptiness is computed on save
and on creation, and a backfill migration marks existing non-empty
projects. Also cleans up import ordering, fixes README migration path,
and removes stale feedback table migration.

* Use ESNext modules and bundler resolution

Update packages/db tsconfig to emit ESNext modules and use 'bundler' moduleResolution. This enables modern ESM output and bundler-style resolution for the db package (keeps outDir and rootDir unchanged).

* feat(editor): add dark mode theme and grid visibility toggle

Add theme state to viewer store with light/dark modes, dark-aware
lighting and background colors, grid show/hide toggle in settings,
and theme toggle buttons in the sidebar.

* Add ground occluder, animated lighting & UI tweaks

Introduce a ground occluder and smoother animated lighting while adjusting editor UI and icons. Viewer: add GroundOccluder (uses polygon-clipping to union slab/zone polygons) and AnimatedBackground, integrate both into the Canvas; improve Lights to interpolate intensities/colors/ambient for smooth theme transitions. Editor: refactor sidebar header to support inline project title editing and move the theme toggle; replace some lucide icons with image assets and add a settings icon (apps/editor/public/icons/settings.png). Also add polygon-clipping to the viewer package dependencies.

* Update dark mode background color and clean up imports
