test(physics): Phase W triage — fix stale GetMaxSpeed tests; file #104 (particle cell-clip deferral)

Browse source 
GetMaxSpeed deliberately does NOT branch on ForwardCommand — it returns RunAnimSpeed x run-rate as the InterpolationManager.AdjustOffset catch-up speed (doc comment + ACE MotionInterp.cs:670-678, retail-verified; the slow catch-up fixed the 1-Hz remote-blip). The 3 failing tests (WalkForward/WalkBackward/Idle) asserted a REMOVED command-branching design. Consolidated into one [Theory] pinning the no-branch contract across commands.

Also files #104 (LOW): scene VFX particles not clipped to the PView visible cell set — deferred out of the Phase W seal (entity bleed already gated by Stage 5; scene particles depth-tested; sky particles scissored). Needs OwnerCellId plumbing (~6-8 files).
