- Core counters: messages processed, sessions, queue depth, uptime, active requests, errors
- Model performance table: recent calls with latency, tokens/sec, provider, status
- Event stream: scrollable log with color-coded levels (error/warn/info)
- Active requests: in-flight request table with session, channel, duration
- Channels grid: existing channel status cards preserved
- Dual timer refresh: 3s for metrics/events/requests, 10s for health/channels
- Targeted DOM updates via getElementById for flicker-free fast updates
- Add SPA shell with hash-based router, sidebar navigation, and WebSocket RPC client
- Add dashboard page with system health cards, channel status, and auto-refresh
- Add chat page with session selector, streaming tool events, and markdown rendering
- Add sessions page with list, history viewer, and delete functionality
- Add settings page with hook pattern editor, tool list, and config viewer
- Add backend handlers: sessions.delete, sessions.switch, system.channels, system.usage
- Wire channelRegistry into gateway server for channel status reporting
- Extend static file server with .mjs, .png, .ico, .woff2 content types
Refactor GatewayServer to serve HTTP and WebSocket on a shared
http.Server. Add static file serving with path traversal protection,
a dark-themed dashboard (system health, sessions, tools) and a
WebSocket chat interface with streaming tool events and markdown
rendering.
