- cache.py:38: Add explicit type annotation for redis.get() return value to resolve mypy no-any-return
- rate_limit.py: Remove duplicate forward-declaration block (dead code, mypy no-redef)
- conftest.py: Remove one excess blank line to satisfy ruff format check
All three fixes verified locally: ruff check ✅, ruff format ✅, mypy ✅
