OpenClaw 串联监控、修复、PR 与预览环境，实现自愈式研发流程

Merge it. Taylor demos the full SDLC of 2026: Nightwatch catching an error, AI fixing it and opening a PR, Cloud creating a preview environment, @openclaw calling to ask if he wants to merge the PR. No code touched. Fully self-healing app. https://t.co/fjVDtJn81R
