Orkuncakilkaya c8a588b2de escape (fix): the arena took ludic.ui's pooled nodes - a generic's call and an unknown callee now keep what they are handed ...

memory_final's gate crashed in all 13 scenarios at the first frame of play, R3D_ARENA_CHECK=1 reading
0xDD in ludic.ui's nd_take: a node the pool keeps had come from the frame's scratch. Two holes:

- a call to a generic (ui_kept(list, n)) names the generic, and the analysis knows only its instances
  (ui_kept$UiNode), so the callee looked unknown - and an unknown callee was taken to keep nothing.
  A generic's call now reaches every instance, and an unknown callee keeps everything it is handed,
  but for a short list of intrinsics known to keep nothing; view() shares its list's storage.
- a push's growth into a parameter's list was LOCAL whenever the list was not seen kept, though a
  parameter may be a state's list. A site is LOCAL now only when its class is neither ESC nor HEAP.

examples/lang/arena_pool.ludic is the shape (a pool keeping records across frames through a generic
push): built with --arena it prints '7 3498' poisoned on every reset and with the arena off, in
ludic-dev test. On the valley every ludic.ui pool site is kept; 5480 sites local, 6431 kept.

Also, from ECS: a record's field defaults are stored into it when it is made, a global's initializer
is kept, and a component's own functions are frame roots (they run while its page is open).
