fix: prevent pending state failure in window platform interface

Remove Qt::QueuedConnection and value comparison to ensure pending
operations always execute synchronously. QueuedConnection fails when
stack variables go out of scope before execution. Removing the early
return prevents state inconsistency when initial values match desired
values. Treeland protocol currently lacks configure support, so all
features must apply immediately.
