A step onto an occupied tile is now an attack: the geometry rule is checked
against terrain only and the target tile decides between move and bump.
Entities carry an attack stat; at zero hp they are removed. The sim reports
Attacked/Died through an event queue the game drains after every movement
window — the seam for sound, log, camera effects and spawns. Click-to-move
treats an occupied goal as a target but detours around entities in the way;
the player's death ends the game.

Occupied tiles now block movement through World::blocked, the one predicate
the sim and the pathfinder share. Entities carry an EntityKind so the sim
knows which ones to think for; Sim::think gives each NPC a random king move
one window in four. Intents execute in id order so contested tiles resolve
deterministically.

Move chunk, entity, world, map, sim and load_world into a new sim library
crate together with the game rules from shared (player_action, action_delta,
delta_action, step_allowed, tile_collidable, tick constants). shared keeps
only the wire types and re-exports the rules, so server and client compile
unchanged. First step toward a local single-player build.
