Final polish: restore SIGUSR1 under visibility gate, drop unused import

- SIGUSR1 stats dump moved above the render gate in runTerminal so it
  fires even while the surface is hidden (regression from the gate
  migration).
- Remove unused `const wl` import from src/frame_loop.zig; the module
  doesn't reference wl directly — adapter casts happen in wayland.zig.
