fix(hyprland/window): avoid stale state during IPC refresh

The window module re-entered the same shared_mutex while refreshing IPC state:
update() took the lock and then called queryActiveWorkspace(), which tried to
lock it again. That is undefined behavior for std::shared_mutex and could
manifest as a deadlock.

Remove the recursive lock path and reset the derived window state before each
IPC refresh. That keeps solo/floating/swallowing/fullscreen classes from
sticking around when the client lookup fails or a workspace becomes empty.
