FerrisPad v0.9.5-rc.2

Fixed

• Update Available Dialog on Wayland: The "Update Available" dialog opened from the update banner no longer freezes the UI. make_modal(true) on a freshly created window left the dialog undecorated and ungrabbed on Wayland/GNOME (and stopped the parent window from receiving input — menu bar, tab bar, and the dialog's own buttons all stopped responding). Now uses the same parent-centering pattern as the session picker and font picker.
