fix: native XDG client rendering — schedule frame on surface commit 

Added permanent surface_commit_listener to wl_toplevel_view that calls wlr_output_schedule_frame on every client buffer commit.
Previously only the initial-commit listener existed, which removed itself after sending the first configure — subsequent buffer updates (typing in foot/xterm) were not triggering re-renders.
