Load-time attribution: the minute is the renderers' entity-make streams

Browse Source 
Measured (loadphase markers + queue blocker dump): renderer LoadMission
31ms, model loads 0.2s -- the teal->green minute is the LoadingMission
ready-gate (IsPriorityEmpty counts timed events too) waiting out the
THREE renderers' entity-make streams: every entity/subsystem creation
posts message 3 to each Renderer receiver (classIDs 8/30/36 =
video/audio/gauge), hundreds deep per queue, draining across the whole
window (the audio renderer's share is why sound starts mid-load).

Instrumentation kept: [loadphase] markers (renderer span + busy-pass
counter) always on; GeneralEventQueue::DumpBlockers + the class-named
DumpData fallback behind BT_LOAD_DIAG=1 (hundreds of lines per load).
Optimizing the drain (batching/budget) is an open perf item --
deliberately untouched before the 8-player night.
