nx_game_render.nx

nx_game_render.nx -- LIB: the GAME domain CONSUMER for the Nishi builder. Resolves game emitters from the universal catalog by id (level/mechanic/entity/tilemap) and RUNS them as a deterministic, sovereign spec->runtime simulation -- no LLM at runtime, no JS, no external fetch. Closes the game loop the same way nx_web_render closes web: build -> teach -> grow -> CONSUME. Growing the catalog grows what plays, no code change. The seeded game specs describe a 2D platformer, so the runtime is a faithful deterministic auto-runner over a 1-D track derived from the level spec: the hero traverses, collecting every coin and clearing every patroller the level declares, jumping with the mechanic's physics, and reaching the exit. Every observable (coins, foes, damage, jump apex, exit tick) is a pure function of the catalog DATA -- so the gate's asserts prove the spec actually drives the run, not a hardcode. Integer-only (NishiLang has no floats): decimals like gravity=0.6 are parsed to milli fixed-point (x1000). license_tier: ORIGINAL
