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

{
Issue #34232 is harder because it spans schema/index design, migration and deduplication of existing data, null-safe conflict handling, concurrent writes, and spend-reporting correctness. Issue #27113 is comparatively localized to the Vertex token-counting call path with focused regression tests.
