feat: tier source badge + VM resource suggestions

- Tier badge (#9): addMessage() gains source param; sourceBadge() maps source string to KB/GROQ/CLAUDE/OLLAMA pill rendered after typing finishes; sendMessage() passes data.source through; CSS badges styled with domain colors
- VM suggestions (#10): vm_suggestions intent queries 24h avg CPU+MEM per agent, flags hosts with >80% avg CPU, <5% CPU on 2GB+ RAM, >85% avg MEM, or <25% MEM on 2GB+ RAM; 8 KB intents; say "VM resource suggestions" or "optimize VMs"
