Create USD Proxy

Generate a low-detail proxy mesh as a sibling of a source prim hierarchy, then mark the two with USD purpose so downstream tooling can pick render vs. proxy automatically. The result is roughly:

/World/Asset             ← source (untouched), purpose = render
/World/Asset_proxy       ← merged + decimated mesh, purpose = proxy

Use this skill when a user asks to:

• Create a proxy / LOD stand-in for a hi-res asset
• Speed up viewport interaction by giving downstream tools a low-poly fallback
• Set up a render/proxy pair so DCCs can swap representations via USD purpose
