Backport typing.override via typing_extensions, lower requires-python to >=3.11, add 3.11/3.12 classifiers and ruff target. Also backport typing.get_protocol_members (3.12+) in test files via typing_extensions, which ty caught when the floor moved to 3.11.
On Python 3.11 the move_on_after cancellation inside broker.ping() unwinds through the test task and coverage.py's C tracer drops the test frame's trace function for the rest of the body, so the trailing assert reads as uncovered (99% < 100% gate) even though it runs and passes. 3.12+ uses sys.monitoring and is unaffected. Awaiting the probe via asyncio.create_task keeps the cancellation inside the child frame, restoring line tracing. Behavior is unchanged: ping(timeout=0.05) still returns False on a hung probe.
…version Without an explicit pin, uv sync selects an interpreter via discovery order (no .python-version/--python set), which works today but relies on a heuristic that could regress to always picking the newest. Pin lint to 3.13 and each pytest leg to its matrix version, matching the db-retry/sibling convention.

Summary
Lowers the supported-Python floor from 3.13 to 3.11, so the package installs and runs on 3.11, 3.12, 3.13, and 3.14. Pure-Python library with no compiled extensions, so this is a source-compatibility + metadata change plus a wider CI matrix. Mirrors the change shipped in the sibling repo
