DeeJanuzandClaude Opus 5.5 d5a15ebc36 Input relay: never block on the pointer helper's socket ...

The relay sent to @ft_pointer_helper on a blocking socket. When the helper stalled, a
layout placement or grabprobe holds it for seconds while ft-gazed keeps filling its socket at
90 Hz, the relay's one loop blocked with it: keyboards, the volume keys (which must never
reach gamescope), and pausing all stopped until the helper read again.

The socket is non-blocking now. A command the helper doesn't take (EAGAIN) waits in a queue,
and everything after it queues behind it so the order holds; tick() sends what it can on each
loop, and the select timeout drops to 20 ms while anything waits. Mouse moves add up into one
queued move. A scroll notch is dropped rather than queued, since scrolling seconds late is no
use; its release still goes. Presses, releases, show, hide, and the rest are kept, so no
button stays down. The queue holds at most 512 commands. While paused, the configured
pointer's queue still drains, so the releases and "hide" from standing down arrive. A
"vrbind" that hits a full socket is sent again on the next loop instead of being lost.
