v0.55.3

Dashboard Closure

• Split the Integration workbench into core Agent OS closure, remote channels, and optional upgrades so customers can distinguish local readiness from external Feishu/Bridge setup.
• Replace raw Feishu/Lark authorization JSON with concise reason, hint, and upgrade-command feedback.
• Improve desktop and mobile Integration layout with a clear current blocker, grouped next actions, and responsive closure score cards.

Verification

• Rebuild the dashboard after the version bump, run dashboard API regression tests, and validate the updated Integration page against E:\project\qwen-project\blog with Playwright screenshots and scale smoke.
