Agent-led browser cards and OpenMuse mobile demo

[jerelvelarde]

Summary

Asking OpenMuse to read Hacker News or summarize a website now opens the agent’s browser directly from chat. The inline tool card shows progress, the real page preview, and a secondary Take control action. Browser profiles persist across chat turns and app reloads; old source cards cannot display a different page after that session moves on.

Adds a reproducible pnpm dev:demo runner using CopilotKit AI Mock for scripted model responses and a separate real Chromium worker for all navigation and reads. The README hero is a 38-second, 16:9 iPhone recording with OpenMuse 🪁 branding, a centered repository link, and an explicit AI Mock disclosure. Canonical links now point to CopilotKit/OpenMuse, and the requested default-data sentence is removed.

Validation

• Formatting/lint; server, mobile, and browser-worker types.
• 149 tests pass, including actual CopilotKit tool streaming, failures, cancellation, owner scoping, session reuse, and AI Mock routing.
• Server build, web/iOS/Android Expo exports, frozen lockfile, and real Chromium lifecycle check pass.
• Native iPhone: Hacker News request → full app relaunch → CopilotKit request retained the same browser session; takeover displayed the live page.
• Independent review completed with no outstanding findings after fixing local thread identity.
• Video: 1920×1080, 30 fps, 38 seconds; 1,140 frames checked with no reload banners. README relative and external links resolve.

The recording scripts the model; it does not establish live-provider reasoning quality or CopilotKit Intelligence acceptance. Browser execution and page results are real. The Linux computer implementation is unchanged.
