calic 497c139727 fix(map-editor): v0.2.0b.1 — bind blob_rect_stone material so Auto-Tile renders

work.map.json was still schema-v2 with the legacy fa_terrain_v1
atlas — neither has a `material` field on its layers, so the
renderer's vertex/blob path never fired and Auto-Tile painting had
no visible effect (the set_vertex writes landed but the renderer
fell back to the cell-tile path that doesn't consume them).

Migration:
 - schema_version 2 -> 3
 - size 4x4 -> 16x16 (room to paint)
 - atlases: fa_terrain_v1 -> blob_rect_stone (S-V2E2-RM-Blob 14-slot
   atlas from lib-asset.prototype-blob-geom)
 - layers: surface + wall, both with "material": "blob_rect_stone";
   vertices+overrides start empty (lib-core.maps lazy-allocates on
   first set_vertex)

Manifest:
 - asset_aliases: fa_terrain_v1 -> blob_rect_stone (lib-asset.
   prototype-blob-geom)
 - deps: drop prototype-fa-starter, add prototype-blob-geom 0.1.0

sporel-module-map-editor

Interactive map editor for v2 Sporel map files. Click-to-paint, vertical layer-chip overlay on the left edge, collapsible atlas+tile picker bottom-left.

Run

Default — edit the module's in-place work map:

bash scripts/run-map-editor.sh

With a target — copy a real map in, edit, copy back out:

bash scripts/run-map-editor.sh ~/Projects/Sporel/sporel-modules/spine-prototype/maps/demo.map.json

UI

Layer chips (left edge, vertical): top-of-stack down. Rf at top toggles roof-edit mode; the other eight chips select the active layer.
- Left-click = set active layer (or toggle roof mode)
- Right-click = toggle layer visibility (Rf chip ignores right-click)
Atlas + tile picker (bottom-left): collapsed chip shows the active tile. Click to expand; click again or outside to collapse.
Status chip (bottom-right): current mouse-cell coordinate plus a * when the map has unsaved changes.

Hotkeys

Key	Action
`Left click` on map	Paint cell with active tile (or set roof flag in roof-mode)
`E`	Erase the cell under the mouse
`R`	Cycle rotation 0 → 1 → 2 → 3 → 0
`S`	Save to disk (overwrites the work map)
`Esc`	Quit

Limitations (v0.1.0)

Tile thumbnails in the picker render as gray placeholders with tile-IDs as text — lib-core.maps v0.4.0 does not expose per-tile UVs to Lua, so visual thumbnails are a v0.2.0 task.
Atlas list in the picker is purely informational; if a map declares multiple atlases, the active atlas is set from state.lua defaults at startup and cannot yet be switched via UI (v0.2.0 hit-tests inside the expanded picker).
Engine bindings engine.render.draw_rect_lines and engine.render.draw_line are not yet registered — active-chip borders, hidden-layer strikethroughs, and the entity-slot divider will trigger runtime errors when their code paths execute. Adding the bindings is a small engine-side follow-up.
No undo/redo, no multi-tile brush, no entity placement, no heightmap editing — see the design spec §1 for the full out-of-scope list.
