petere 2b3fd54934 feat: harden engine config, discovery and backpressure stats
- config: validate port/quality/fps/source/stream-index ranges on load
  and before engine start (flinger.Config.Validate)
- discovery: add Announce option to disable multicast (GUI checkbox,
  CLI --no-announce); absent JSON key keeps the default true
- backpressure: count dropped frames in the TCP sender, expose via
  engine Status and a live counter in the GUI status label
- docs: record M3/M4 decisions and X11 coverage via the portal backend

// Command teleportfling is a standalone sender for the Teleport protocol.
//
// It captures a Wayland screen (PipeWire via xdg-desktop-portal) plus the
// system's default audio output and streams them over TCP as the Teleport
// protocol, announcing itself on the LAN multicast group so an OBS instance
// with the obs-teleport plugin can discover and decode the stream.
//
// This is the headless/CLI entry point; the engine lives in
// internal/flinger. A desktop GUI with settings and a system tray is in
// cmd/teleportfling-gui.
//
// Usage:
//
// teleportfling [--name NAME] [--port PORT] [--quality 1..100]
// [--fps N] [--source screen|pattern] [--audio]
// [--stream-index N] [--duration SECONDS]
//
// --source pattern selects the M1 synthetic test pattern (colour bars with a
// moving box) instead of real screen capture, which is useful for testing
// without granting screen-share permission.
