feat: M0 capture→encode pipeline + M2 GameStream host (pairing, RTSP, video)
M0 (lumen-host) — verified on NVIDIA RTX 5070 Ti / Ubuntu 25.10: headless wlroots → xdg ScreenCast portal → PipeWire → NVENC HEVC → playable file, with each access unit round-tripped through a lumen_core host↔client Session (FEC + packetize + reassemble), 0 mismatches. - capture.rs: SyntheticCapturer + portal capture (ashpd 0.13 + pipewire 0.9), format-aware - encode/linux.rs: NVENC via ffmpeg-next 7 (BGRx/RGB → rgb0, no host-side swscale) - m0.rs: capture→encode→file + lumen-core loopback verification M2 P1 (lumen-host gamestream/) — a stock Moonlight client pairs + launches, verified live: - mDNS _nvstream._tcp + nvhttp /serverinfo (HTTP 47989, mutual-TLS HTTPS 47984) - 4-phase pairing: PIN→AES-128-ECB / SHA-256 / RSA-PKCS1v15 / X.509, custom rustls ClientCertVerifier for the mutual-TLS pairchallenge - /applist, /launch (rikey/rikeyid/mode), hand-rolled RTSP (OPTIONS/DESCRIBE/SETUP×3/ ANNOUNCE/PLAY, one-request-per-TCP-connection per moonlight-common-c's read-to-EOF) - video.rs: GameStream RTP + NV_VIDEO_PACKET wire packetizer, data-shards-only (0% FEC, clean-LAN), unit-tested (single/multi-block) Docs: docs/m2-plan.md (phased plan) + docs/research/ (ground-truth protocol spec). Bootstrap/setup updated for the verified path (libnvidia-gl, render/video groups, GPU EGL, pipewire 0.9). Workspace clippy-clean, tests green.
