* fix(evdev): monitor remapper virtual keyboards ungrabbed
On Wayland the device hub grabs every discovered keyboard and clones it
via uinput so the dictation shortcut can be suppressed. With a remapper
like keyd running, the hub grabbed its virtual keyboard too, and the
remapper grabbed the clone in turn (keyd's default [ids] * matches it):
forwarded keys went to the remapper instead of the compositor, so users
could not type at all, and each forwarded event looped back through the
chain.
Detect virtual keyboards by their sysfs device path (uinput-spawned
devices have no physical parent and live under /devices/virtual/input),
falling back to known remapper names when sysfs is unreadable, and
monitor them ungrabbed. Their events still reach the listener, so
shortcuts bound to them keep working; only suppression is lost, which a
grab could never provide anyway since the remapper re-emits on a device
we cannot hold. keyd reports BUS_USB for its virtual devices, so the
bus type cannot discriminate; the sysfs path can.
Fixes#930
* test(evdev): annotate new #930 test mocks
Satisfies the repo rule that every function signature carries type
hints, including test fixtures.
