Without the camera scope, maps.draw_map() rendered the map at
screen coords starting at (0,0) regardless of camera.set_target,
and screen_to_world's inverse produced bogus cell coords (mouse
in screen-center mapped to top-left tile). Spine-prototype's
render() shows the right pattern: world-space draws inside
camera.begin/finish, screen-space overlays after.
The engine module-lifecycle looks up HOOK_RENDER by the global
name 'render' (engine_module_lifecycle.c:166). The previous draw()
function was a global with no caller, so the editor's UI never
rendered — the engine fell back to its 'no render hook defined'
placeholder.
The engine's Lua sandbox rejects require() for non-declared-dep
module names like 'src.state'. Multi-file modules in this codebase
either inline everything (spine-prototype, vagrant-skeleton) or
use dofile (lib-sporel.launcher). For three modules that share a
state singleton, dofile would cause state divergence. Cleanest
fix is to inline all three into init.lua via IIFE-wrapped local
module tables, preserving the file-internal namespacing while
satisfying the sandbox.

init.lua loads the work map, binds hotkeys (E/R/S/Esc), tracks
mouse-cell per frame, dispatches clicks to the UI hit-tester
and falls through to paint-cell for unconsumed map-area clicks.
run-map-editor.sh handles copy-in/copy-out for a real target map
or runs in-place against the module's work slot.
Empty launchable module with deps on lib-core.maps 0.4.0, render,
camera, input, and the fa_terrain_v1 asset alias. Renders the
default 4x4 empty work-map; interactive editing wired in
subsequent commits.
