megaproxy f67c12c51f Clear designation tile-highlight when jobs complete
Each entity completion handler (wall/floor/door/bed/torch/workbench/crate
/tree/rock/big_rock/grave_slot) now calls World.clear_designation_at(tile)
so the orange/blue/etc. highlight overlay disappears with the job.
BigRock iterates its footprint to clear all four tiles.

World.designation_ctl is set during the scene boot wire-up; the helper
no-ops when the controller is absent (e.g. headless tests).

class_name Torch extends Node2D
## Torch furniture entity — buildable wall-hung or floor-standing light source.
##
## Rendered as a small stick + wrapped head + flame using _draw() in the same
## 3/4-perspective convention as Wall / Bed / Workbench. Ghost state (40% alpha)
## while construction is in progress; solid + lit once _completed.
##
## Light model (docs/architecture.md "LightingSystem"):
## Emits a PointLight2D with a procedural radial-gradient texture (soft
## falloff). The Godot visual light is additive with CanvasModulate for
## night-time darkness. The sim-side light radius (LIGHT_RADIUS tiles,
## Manhattan distance) is registered with World.light_sources so that
## is_tile_lit() can answer "in darkness" thought queries cheaply.
##
## Light-source duck-type interface (shared with Hearth / Workbench):
## is_on() → bool
## get_light_tile() → Vector2i
## get_light_radius() → int
##
## Build model (same BuildJob interface as Wall / Bed / Workbench):
## BUILD_TICKS ticks via the standard BuildJob toil; PointLight2D enabled
## only after _complete().
##
## Save/load: to_dict / from_dict capture tile, label_text, build_progress,
## _completed, _is_on. Phase 16 wires these into the full save layer.
##
## World registration: World.register_light_source / World.unregister_light_source
## called from _ready / _exit_tree.
const TILE_SIZE_PX: int = 16
## Sim ticks to build a torch (30 ticks ≈ 1.5 sim seconds at 1×).
const BUILD_TICKS: int = 30
## Sim-side light radius in tiles (Manhattan). Max 8 per architecture.md.
const LIGHT_RADIUS: int = 6
## Pixel size of the procedural radial gradient used for the PointLight2D.
## Larger values give a smoother falloff; 64 is sufficient for a 6-tile radius.
