feat(compiler): the built-in ECS's stores grow - 100 000 entities, where 1024 was the wall

Browse source 
Every per-entity store (@S_ components, @H_ flags, alive, kind, freelist, owners) is a heap block
L_grow doubles from 1024 as L_alloc hands out a slot past it, the new slots zeroed; each site loads
the store's base where it indexes it (ecs_base, its registers %ecsb* so a raw function's t0 labels
cannot collide). Prop.has bounds against @L_cap, Pool.capacity answers it, a mod's registered
stores grow with the rest, every main grows the stores once before anything reads them. A snapshot
records its slot count first and a load grows to it before reading back. The overflow stop of
1c7ce84 is gone with the wall. ludic-dev test 305 passed, selfhost-test 33 passed; 1000 / 5000 /
100000 entities spawn and count.
