Use fixed fakeredis fork and achieve 100% test coverage
Fixed xpending_range compatibility issue with fakeredis by using our fork that returns all 4 required fields (message_id, consumer, time_since_delivered, times_delivered) instead of just 2 fields. Changes: - Updated pyproject.toml to use fakeredis fork with xpending_range fix - Added allow-direct-references = true to hatch metadata config - Updated test_memory_backend_reuses_server to properly cover all lines - Achieved 100% test coverage with memory backend fakeredis fix details (in zzstoatzz/fakeredis-py@fix-xpending-range-fields): - Changed pel dict from Tuple[bytes, int] to Tuple[bytes, int, int] - Initialize times_delivered=1 when messages are first read - Increment times_delivered when messages are claimed - Return all 4 fields in pending() method matching real Redis behavior
