Requiring 3.13 meant the device needed an interpreter the distribution does not
have, which is what dragged uv in, and uv then had to be matched to the Pi's
32-bit userland by hand and to build Pillow from source because no armv7 wheel
exists for a 3.13 ABI. Dropping to 3.11 removes all of that: apt provides the
interpreter and piwheels has prebuilt armhf wheels for the native dependencies.
The 3.13-only syntax was shallow - PEP 695 throughout, which converts back
mechanically:
type X = Y -> X: TypeAlias = Y
type Handler[E: Event] -> E = TypeVar("E", bound=Event) plus a plain alias,
which is generic anyway because it carries a TypeVar
def f[T: Bound](...) -> a module-level TypeVar
Also drop the one @override (3.12, and static-only), and stop the lirc test
harness calling Server.close_clients(), which is 3.13: the scripted handler now
releases its connection when asked, which is what that call was there to force.
Verified on 3.11.14 - 485 passed, mypy strict clean - and still 496 passed on
the 3.14 dev venv, which additionally has the analysis extra.
