TerrainPlacementService2D

Scene-free terrain placement service: terrain-name -> TileSet-ID resolution, plan building/gating/application, and signal emission. Keeps the terrain paint path directly unit-testable. Usage: var service := TerrainPlacementService2D.new() service.configure(building_state, building_settings) var report := service.try_place_terrain_by_name(&"dungeon_floor", cell, map, owner)

TERRAIN_QUERY_INSET_PX	Field	Boundary-contact tolerance (pixels per side) for terrain collision queries. Physics overlap tests report boundary-touching shapes as hits, and resting rigid bodies penetrate cell boundaries by fractions of a pixel — without tolerance, a box merely touching a cell's edge blocks painting there (platformer: box at rest overlaps the neighbor cell by ~0.0001px on one side and ~0.27px below, both read as blocked). The inset keeps hairline contact from counting as occupancy while genuine overlaps still block. Mirrors the precedent in [method TilePaintCollisionRule._cell_query_shape], which insets its feature-layer query for the same reason.
