mikael-lovqvists-claude-agent 54d48c9c8e Add no-signal animation to display windows ...

When a viewer window has no incoming stream, renders animated analog-TV
noise (hash-based, scanlines, phosphor tint) at configurable fps (default
15) with a centred "NO SIGNAL" text overlay.

- xorg: FRAG_NOSIGNAL_SRC shader + xorg_viewer_render_no_signal(v, time, noise_res)
- main: Display_Slot gains no_signal_fps + last_no_signal_t; display_loop_tick
  drives no-signal render on idle slots via clock_gettime rate limiting
- protocol: START_DISPLAY extended by 2 bytes — no_signal_fps (0=default 15)
  + reserved; reader is backward-compatible (defaults 0 if length < 18)
- controller_cli: no_signal_fps optional arg on start-display
- docs: protocol.md updated with new field
