frame allocs (25.2): what a frame can come to allocate, counted and ratcheted

Browse source 
deps_reach's graph gains the handlers and each @On body (an emit reaches its event's listeners).
Roots: a handler in a frame phase, every reducer, an @On body, and a function stored as a System's
tick. Every allocating construct in what they reach - new, a list literal, push (grow), text built
by + or a template, words/floats/buffer/bytes - is a falloc line with the shortest chain from a
root (root>..>last six), and the program's count is frame_allocs. @alloc_ok("why") on a function or
a handler takes it and what only it reaches out; the reason is required. ludic deps --allocs lists
them, and frame_allocs is a number --check ratchets. Maroon Lake starts at 2661.

Not yet: @frame on a step list's field (only 'tick' is a root field so far), statement-level
@alloc_ok, the three lints.
