Summary

This is a focused slice from #27488 with only two user-facing outcomes:

• Lock Screen / Dynamic Island shows OpenClaw connection health (Connecting, Idle, Disconnected)
• Live Activity stale/duplicate entries are cleaned up so users keep one accurate status card

Why this split

The original PR bundled broader UX and architecture changes. This PR keeps scope small, testable, and low-risk for shipping.

Included

• ActivityKit + widget target wiring for iOS app
• Minimal Live Activity manager and shared attributes
• Connection lifecycle hooks in NodeAppModel to keep status current
• Duplicate/stale activity cleanup before reuse

Not included (intentionally)

• AI-generated title/completion behavior
• Large UI/navigation/theme changes
• broader onboarding/chat flow rewrites

Attribution

Core idea/source work came from #27488. Thank you @leepokai for the original implementation direction.

• pnpm ios:gen (xcodegen) passed
