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

Add file attachment support with SHA-256 content-addressable storage,
automatic deduplication, MIME detection, and garbage collection for
orphaned files. Includes MCP tools (upload_attachment, download_attachment,
gc_attachments), REST API endpoints for Web UI, and comprehensive tests.

Add comprehensive trace logging and observability features:
- Enhanced trace store with owner-scoped queries, filtering (agent, action,
time range), pagination, streaming export, and retention cleanup
- REST API endpoints: GET /api/traces (list with filters), GET /api/traces/export
(streaming JSON/CSV), GET /api/traces/stats (action counts)
- Owner isolation enforced at every layer (store, API, tests)
- Hand-rolled Prometheus metrics (pure Go, zero CGO): traces_total,
traces_by_action, errors_total, active_agents at GET /metrics
- Configurable slog JSON handler with --log-level flag
- Request ID middleware for cross-referencing logs and traces
- Batch trace writing (64 entries or 100ms flush interval)
- Background retention cleanup via --trace-retention flag
- SQL migration 002 adds owner_id column and composite indexes
