fix(allocs): ludic.update, steps, effects and telemetry at 0 frame allocs and 0 keeps

ludic.update: whether this copy can update itself is worked out once, when the updater is configured
(the panel asked every frame, building the path to the executable each time); the notes are a list
the state keeps, filled by update_notes_for when the version or the language changes, which the
game calls from its update tick. The feed's address is declared (once, when a check starts).
ludic.steps, ludic.effects, ludic.telemetry: what is left is made on an event and declared with its
bound - an arc's tables, a chapter's columns, a step's fact, an effect's start, end and clear, the
fact pool's growth, the player id, a props record's nesting stack - and two pushes into a caller's
kept list, at most a chapter's steps and the ring's size.
