Add complete Web UI infrastructure:
Go backend:
- REST API handlers for messages, agents, channels (internal/api/)
- SSE hub for real-time event streaming
- Session-to-owner middleware bridging auth sessions to API context
- SPA file server with go:embed for static assets
- GetMessageByID on MessagingService, RevokeKey on AgentService
- Updated router with RouterConfig for full service wiring
Svelte 5 SPA (web/):
- SvelteKit with static adapter for SPA mode
- Tailwind CSS with dark mode (class-based, localStorage persisted)
- API client with auto-redirect on 401
- SSE client with exponential backoff reconnect
- Pages: Login, Dashboard, Conversations, Channels, Agents, Settings
- Components: Sidebar, Header, MessageList, ComposeForm, AgentCard, TraceViewer
- Responsive layout with mobile sidebar toggle
Build:
- Placeholder index.html in internal/web/dist/ for go:embed compilation
- Updated Makefile web target to copy build output
- All existing Go tests pass, CGO_ENABLED=0
