Adrian RatiuandClaude Fable 5 6e0b50567e fix(sway/ipc): don't mistake events for the subscribe reply
Ipc::subscribe() assumes the next message on the event socket is the
reply to the IPC_SUBSCRIBE it just sent.

When a module subscribes more than once (sway/workspaces subscribes to
"workspace" and then to "window"), an event from the first subscription
can arrive before the reply to the second one. The payload check fails
and the thrown exception permanently disables the module for that bar.

This is easy to hit when bars are (re)created on output hotplug, since
sway emits a burst of workspace events at exactly that moment while
moving workspaces to the new output:

[warning] module sway/workspaces: Disabling module "sway/workspaces",
Unable to subscribe ipc event

Fix it by skipping over event messages (type high bit set) until the
subscribe reply is found, re-emitting them on signal_event so none are
lost.

Fixes: #5218
