Wire the first end-to-end pipeline: capture -> encode -> packetize -> UDP -> depacketize -> decode -> render. - UdpRtpTransport: raw POSIX UDP sockets (IPv4 via getaddrinfo), a receive jthread woken by socket close on stop; port 0 skips binding so the sender uses an OS-assigned source port. ASIO stays deferred to the signaling phase per ARCHITECTURE.md. - SdlRenderer: SDL3 window/renderer with RGBA texture upload; the texture is recreated on resolution change. RendererFactory now returns RendererResult so SDL init failures carry a message, mirroring the codec/capture error patterns. - screencast binary: parse_cli plus SenderPipeline/ReceiverPipeline per the app scaffolds; the sender creates its encoder once capture reports real dimensions, the receiver keeps a bounded 3-frame queue to hold latency down and renders on its own thread until the window closes. cli argv signature fixed to 'const char* const*' so main's argv converts implicitly. - Encoder: drop AV_CODEC_FLAG_GLOBAL_HEADER so libx264 repeats SPS/PPS in-band at each keyframe -- the receiver decodes from the bitstream alone, which also makes mid-stream joins and later PLI recovery work without out-of-band parameter negotiation. The round-trip test now exercises exactly that path. - tests: new udp-loopback integration test pushes synthetic frames through a real localhost socket and decodes 10/10 frames with the right dimensions; valgrind clean (loopback + codec). meson test 4/4. Manual validation on the desktop (receiver window shows the captured desktop) is documented in docs/RUNBOOK.md.
