Implements Phase 1-2 of multi-tenancy support using a directory-per-tenant
strategy that preserves existing file-based persistence.
Key changes:
- Add MultiTenantPersistence manager for org-scoped config routing
- Add TenantMiddleware for X-Pulse-Org-ID header extraction and context propagation
- Add MultiTenantMonitor for per-tenant monitor lifecycle management
- Refactor handlers (ConfigHandlers, AlertHandlers, AIHandlers, etc.) to be
context-aware with getConfig(ctx)/getMonitor(ctx) helpers
- Add Organization model for future tenant metadata
- Update server and router to wire multi-tenant components
All handlers maintain backward compatibility via legacy field fallbacks
for single-tenant deployments using the "default" org.
- Add MetadataProvider interface for AI to update resource URLs
- Add set_resource_url tool to AI service
- Wire up metadata stores to AI service via router
- Add URL discovery guidance to AI system prompt
- AI can now inspect guests/containers/hosts for web services
and automatically save discovered URLs to Pulse metadata
Usage: Ask the AI 'Find the web URL for this container' and it will:
1. Check for listening ports and web servers
2. Get the IP address
3. Verify the URL works
4. Save it to Pulse for quick dashboard access
