Deduplicate Hierarchies

Invocation. This is the deduplicate-hierarchies skill. Claude Code also exposes it as the alias /deduplicate-hierarchies. Codex and other agents invoke it by name. Don't reference the alias-only form when writing for a non-Claude agent.

Platform paths. Examples use the POSIX CLI path _build/linux-x86_64/release/bin/usdOptimize. On Windows use _build\windows-x86_64\release\bin\usdOptimize.exe; $Var → %VAR%.
