r3d/runtime: allocs, keeps and births at 0 on this side

Browse source 
render3d: shadow_fit, water_reflection_pass, layer_partition_lods and the
GPU cull's scratch are made with the state; v3_dist is scalar; the pushes
into lists sized at start-up, the caps probe, the table growth, the loads
and the constructors declared with their bounds (one statement a line);
the renderer's name made once with the device; the two error messages
given back; the dead lupine models removed.

runtime: a component's text is held interned in its value cell (one copy
per distinct text), so the getter's own text goes with its frame instead
of being kept by ludic.ui's model - 80 of the 83 keeps.
