Expose minimum_check_interval, reduce task pickup latency (#3500)
* perf: expose minimum_check_interval, reduce task pickup latency

The Docket Worker polls for new tasks every minimum_check_interval
(previously hardcoded to 250ms in pydocket). Expose this setting so
users can tune it, default to 50ms, and override to 10ms in tests.

This cuts average task pickup latency from ~125ms to ~5ms per task.

* perf: reduce task test overhead and eliminate cross-test contamination

- Expose minimum_check_interval setting (default 50ms, 10ms in tests)
  to reduce Docket Worker task pickup latency
- Isolate fakeredis per test via unique memory:// URLs to prevent
  stale _async_blocking tasks from contaminating subsequent tests
- Make client disconnect timeout configurable (default 5s, 1s in tests)
- Add --durations=50 to CI for passive performance regression detection
- Remove 15s timeout band-aids from task test conftest files
- Add explicit @pytest.mark.timeout(10) to cancellation tests
- Fix deprecated FastMCP.as_proxy() usage in test_task_proxy.py
