Add article: OpenUI for Voice Agents with LiveKit

[imaanmulji]

Summary

• Adds a written-content submission for issue Written Content: OpenUI for Voice Agents: Pairing LiveKit with Generative UI for Real-Time Visual Feedback #6.
• Grounds the article in the thesysdev/voice-agent-generativeui reference implementation rather than a broad voice-agent overview.
• Focuses on the concrete event protocol: show_ui, the LiveKit genui text-stream topic, progressive rendering through C1Component, stream cancellation, and action callbacks back into the agent loop.

Notes

This is intentionally differentiated from more conceptual voice-agent drafts by treating the visual layer as an event-driven workspace contract: voice session, visual stream, renderer, action, and cancellation contracts.

Fixes #6
