feat(phys L.2a slice 2): include hit object guid in [resolve] probe

Browse source 
Extends the existing [resolve] probe line to surface
ci.LastCollidedObjectGuid (hit object) + ci.CollidedWithEnvironment
(terrain hit flag) + ci.CollideObjectGuids.Count (when >1) so the
operator can tell WHICH entity the wall is, not just the wall normal.

Tonight's L.2a slice 1 trace caught a clean wall-slide at the
Holtburg-area doorway (n=(0,1,0), 122 hit=yes lines), but had no way
to attribute the hit to a specific entity — the L.2d sub-direction
call (door collision shape vs building wall mesh) needs the entity id
to pick the right fix. This extension provides it on the next run.

Format change for [resolve] hit field:
  Before: hit=yes n=(0.00,1.00,0.00)
  After:  hit=yes n=(0.00,1.00,0.00) obj=0xCC0CXXXX
          hit=yes n=(0.00,1.00,0.00) env
          hit=yes n=(0.00,1.00,0.00) obj=0xCC0CXXXX env nObj=3

Pure additive within the existing PhysicsDiagnostics.ProbeResolveEnabled
gate. No new env var, no new file. Build green.
