Build Shiny web UI for remote code reviews

[jasdumas]

Problem

Voice reviews currently require local terminal access. Remote teams, pair programming sessions, and CI/CD pipelines can't easily use voice review.

Proposed Solution

• Build a counselor_app() Shiny application for browser-based reviews
• Features:
  • WebRTC-based voice capture in browser (no local mic dependency)
  • Visual diff viewer with syntax highlighting
  • Conversation transcript panel
  • Approve/reject buttons alongside voice commands
  • Session history and replay
• Deploy-ready for RStudio Connect, ShinyApps.io, or self-hosted
• API endpoint mode for CI/CD integration

Technical Notes

• Use bslib for theming (match pkgdown Darkly theme)
• WebRTC via JavaScript interop for browser audio capture
• Could use shinyjs or httpuv for WebSocket communication with Pipecat
• Keep as optional: Suggests dependency, not Imports

Acceptance Criteria

• counselor_app() launches browser-based review interface
• Voice works through browser (WebRTC)
• Visual diff with syntax highlighting
• Can approve/reject via voice or button click
