Prism Chat 2.0.0 — major quality-of-life and stability upgrade

Chat & agent improvements
• Redesigned chat UI with provider/model picker, conversation history drawer, and a clearer composer toolbar
• Live research traces show the steps Prism takes (page context, searches, fetches, browser actions) with source chips
• Stronger page-agent control: on-page control banner, safer input handling while the agent is active, and clearer activity feedback
• YouTube-aware context: video metadata, chapters, playback position, and transcript/caption extraction when chatting about a video
• Voice dictation in the composer for faster prompting
• Thinking/reasoning disclosure so you can see how long Prism thought and expand the reasoning trail

Stability & reliability
• Resilient chat retries for transient network/provider hiccups, with clear localized errors for billing/auth failures
• Cross-browser parity with the Chrome build for the same core chat and agent experience
• Privacy controls for embedded web views (private mode and clear site data)

This is a substantial step forward for Prism Chat — not a minor patch.
