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

{
Issue #34378 is harder because it spans configuration schema handling, router registration, persistence into spend metadata, and tiered cost-calculation behavior, with broader compatibility and regression-testing risk. Issue #26250 is comparatively localized to iterator lifecycle cleanup and accompanying async tests.
