🚀 Release v1.22.1 — WebCodecs Resilience & Speed

📝 Summary

This patch release focuses on perfecting the WebCodecs live streaming experience, specifically for environments with high network latency or jitter. By introducing intelligent keyframe caching in the backend and a smarter jitter buffer in the frontend, we've nearly eliminated "black screen" stalls and achieved near-instant stream synchronization.

🛠️ Key Improvements

• 📺 Backend Keyframe Cache: The engine now caches the most recent SPS/PPS/IDR packets, ensuring new WebSocket clients can start decoding immediately without waiting for the next GOP boundary.
• ⚡ Instant Synchronization: Dramatically reduced the time-to-first-frame on live views, especially noticeable on high-latency remote connections.
• 🧩 Smart Jitter Buffer: Implemented a 2-frame micro-buffer in the frontend to absorb network fluctuations while maintaining ultra-low latency.
• 🔄 Stall Prevention: Corrected the frame-dropping logic to prioritize the newest frames, ensuring the stream remains "live" even when network conditions degrade.
• 🛡️ Documentation Sync: Updated SECURITY.md and the system Wiki with detailed troubleshooting guides for WebCodecs and information on resilience mechanisms.

🐛 Bug Fixes

• Fixed a race condition in StreamReader that could lead to inconsistent keyframe cache states under heavy load.
• Resolved a logic error in WebCodecsPlayer.jsx where older frames were incorrectly buffered while newer ones were dropped during backlog clearance.
