fix: prune per-monitor windows on monitor removal (v0.6.15)

Browse Source 
Resume-unlock SIGSEGV: connect_monitor only adds windows to all_handles,
never removes them when a monitor powers off on suspend. gtk4-session-lock
unmaps and drops its own ref, but the GtkApplication and all_handles keep
theirs, so the orphaned window survives until unlock — where destroying it
dereferences its now-NULL monitor association and crashes.

Watch display.monitors() and prune handles whose monitor is no longer
valid, releasing the app ref via remove_window (the lib already unmapped
and dereffed the window — we must not destroy it ourselves).

Revert the earlier idle_add_local_once deferral: the logs proved it
ineffective (crash happens inside the idle trampoline). Diagnostic unlock
logging kept until a suspend/resume cycle confirms the fix.
