a program's states made on first injection, and the ECS stores started at 8 slots

Browse source 
Maroon Lake's launcher watcher - a process that only spawns the game and waits - held 58 MB, 48 MB of
it MALLOC_SMALL. Measured with malloc stack logging it was not the state defaults but L_grow: every
program sized every property type's per-entity store to MAX_ENT (1024) slots at start, 1,583 stores,
entities or none. And every state record was made with its defaults in L_init_globals before Boot.

- emit_lazy.ludic: a program's (not the runtime's) state global is left out of L_init_globals, and
  every read of it calls @S_<global>(), which makes it on first call from its own initializer - after
  every registry and plain global, so a default may read them (the init-order crash cannot come back
  through a state). What a getter makes is declared (@lp_fdecl): a state first touched in play is made
  once and not judged as a frame's keep. A function value's trampoline calls the getter too.
- L_grow starts the stores at ECS_FIRST (8) and doubles as entities come, as it always did past MAX_ENT.

The watcher (with the game's watch step moved before the systems' defs): 57 MB -> 11 MB; the only
state it makes is UiState (14 KB). What is left: AppKit's window, opened by rt_init before main for any
windowed program (~4 MB), and the runtime's font, image and 2D inits (~1.2 MB).

Goldens: the arena, fence, value and json goldens; the 36 ui examples; 30 of the 32 ECS test cases
(sprite_render and sprite_atlas time out under a plain runner with the toolchain before this too).
Package tests: ludic.base, save, settings, i18n.
