Teleport protocol:
- protocol: wire format (Header/ImageHeader/WaveHeader), BT.709 full
range colour matrix, JPEG encode via turbojpeg cgo, WAVE packet builder
- output: TCP sender with per-connection buffered channels and drop-on-overflow
- discovery: multicast announce via peerdiscovery
- cmd: teleportfling CLI with flags, test-pattern frame generator
Verified end-to-end: OBS discovers and renders the stream with correct
colours and motion.
