perf(streaming): scope reveal warmup spatially

Browse source 
Source composite warmup from the canonical published destination neighborhood, including quiesced static and live projections, instead of rescanning the retained Far-tier world after every membership edge.

This lifecycle correction applies to both draw paths, preserving ef1d263337 as the sole G4 visual rollback.
