perf(streaming): reserve destination reveal capacity

Browse source 
Join destination scheduling to the canonical reveal generation, protect its share across every typed frame-budget dimension, and prevent stale work from clearing a replacement reservation. Remove forced incomplete materialization and project retail's centered portal wait cue while the authored tunnel remains active.

Tests: Release build clean; 91 focused reservation/reveal tests; full solution 8,158 passed, 5 skipped.

added immediate generation quiescence and cursored retirement. E4 advances
render/physics/static publication from retained exact receipts. E5 replaced
mutable priority-radius state with the reveal coordinator's exact
generation-scoped destination reservation, protected its share across every
typed budget dimension, removed forced early materialization, and added
retail's centered five-second portal wait cue. E6 deterministic pressure and
physical-local closeout is next.
**Purpose:** Remove update-thread portal transactions.
