Add H.265/HEVC WebRTC video playback support: - H.265 VPS/SPS/PPS parameter set storage and bundling with IRAP frames - H.265 RTP depacketization (single NAL, AP, FU packet types) - Proper RTP timestamp handling for frame ordering - NACK responder for packet retransmission on lossy networks - Browser codec capability detection with user-friendly error messages Bundle libdatachannel 0.23.3 as a submodule: - Ubuntu 22.04 doesn't have libdatachannel in repos - Fedora's 0.21.x has a bug breaking H.265 RTP timestamps (PR #1370) - Auto-builds on first compile via deps-libdatachannel target Enable ENABLE_WEBRTC_PLAYBACK=1 by default. Use ENABLE_WEBRTC_PLAYBACK=0 to disable and reduce binary size. Tested: H.264 and H.265 streams play smoothly in Chrome 136+ and Safari. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
