Configure dynamic hostname access for particle-os VM

- Added Avahi mDNS daemon to VM for hostname broadcasting
- Created update-particle-os-ip.sh script for dynamic IP discovery
- Configured SSH config for both IP and hostname access
- VM now accessible via 'ssh particle-os' regardless of IP changes
- Verified debian-bootc-image-builder project location on VM
