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

{
The right issue is harder because it requires tracing and correcting duration-unit handling across multiple pricing call paths, preserving compatibility for existing callers, and adding targeted regression coverage. The left issue is comparatively localized: adjust unknown-model handling, emit a warning, and update tests for the changed contract.
