calic 25e838c54f feat(map-editor): v0.2.0b — bottom palette + Auto-Tile vertex paint

UI:
 - Bottom palette strip (above status, left of side-panel): 14
   coloured swatches numbered 1-14. Click selects state.active_tile.
 - World-space overlay (Auto-Tile mode only): cell grid + vertex
   dots + snapped-vertex highlight ring.
 - Side-panel + status repositioned to clear the palette band.
 - Cheatsheet updated with the new LMB/RMB canvas + palette rows.

Paint:
 - Auto-Tile mode: LMB on canvas -> maps.set_vertex(active_layer,
   snap.vx, snap.vy, true); RMB -> set_vertex(..., false). Snap is
   computed in update() by rounding world coords to the nearest
   (W+1)x(H+1) vertex; off-map cursor publishes nil.
 - Direct mode: unchanged from 0.2.0a (paint_cell_at with active
   slot + rotation).

Notes:
 - Palette swatches are placeholder solid colours, not real tile
   thumbnails — that needs a tile-UV getter on lib-core.maps, which
   is out of scope for this sub-slice.
 - Transform controls, Direct-Override transform writes, and the
   Decal/Entity sub-selectors land in 0.2.0c/d.

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.
