[BREAKING] OpenClaw 2026.7.2-beta.6: Claude Opus 5, MCP Apps host, session forking, crash-durable state

Large beta covering persistence hardening (quarantine store, crash-recoverable SQLite snapshots, rejection of data-losing schema upgrades), durable message delivery across ten chat channels, conversation rewind/fork with branch switching, and a ticketed MCP Apps host with dashboards. Adds Claude Opus 5, Kimi K3, and GPT Live realtime — realtime Talk now requires a supported OpenAI Platform API key, as the Codex OAuth fallback is rejected. Also adds meeting guests for Teams/Zoom/Meet, a Wear OS companion, and in-process llama.cpp inference.
