Sorting LiteLLM GitHub issues by difficulty to implement. Higher = harder.

The left issue is harder because it involves tracing a regression across protocol translation, structured tool-call serialization, and version-sensitive model handling, with broader compatibility and regression-testing risk. The right issue appears localized to metadata merge precedence and spend-log construction, requiring narrower code changes and validation.
