fix(streaming): retire stale portal-region entities

Browse source 
Port retail's 25-second leave-visibility lifetime over canonical live records, retaining spatially resident and owned entities while using the conservative ACE visibility envelope for nonresident records. Route expiry through the normal generation-safe F747 teardown so animations, effects, physics, and render owners unwind symmetrically.

Replace the append-only modern mesh buffer with coalescing vertex/index ranges and upload each mesh's vertices once instead of once per material. Released zero-reference meshes can now reuse GPU ranges after portal and cache churn.

A connected five-region round trip returned animation ownership to baseline, recreated the starting region on revisit, and held normal FPS. Release build succeeds and all 5,927 tests pass with five intentional skips.
