USD diff, compare feature #245
Description
Is your feature request related to a problem? Please describe.
When editing USD with coding AI agent(e.g, Claude), it is better to have USD specific diff/compare feature to improve handling USD data.
Describe the solution you'd like
in-memory representation of USD(Layer/Stage): Use Prim/Property level diffing(+ compare)
USDA: Use text diff
USDC: Convert to Ascii or in-memory representation, then do diffing in ascii or in-memory.
Additional context
Full text search: Use suffix array algorithm.
Fuzzy text search: Use n-gram hash, or let coding AI(LLM) do that.
