Bones: client-side SetupBones/studiohdr groundwork

- bones.cpp: resolve IClientRenderable via IClientUnknown slot 6, validate it
  against IVModelInfo GetModel, call SetupBones (slot 16) with engine Time()
  (slot 14), and parse the studio header (GetStudiomodel, slot 29) for
  bones/bone names/parents and hitboxes
- cache up to 64 entity bone snapshots, refreshed at ~30 Hz
- helpers: bone_find/parent/pos, hitbox_center (e.g. "head")
- debug probe: HL2H_BONE_DEBUG=1 draws a white marker at each NPC's head
  hitbox center and logs bone count/head position once
