feat: Azure multi-cloud deployment with reorganized structure

[rahul240699]

Azure deployment features:

• Single agent deployment script for Azure VMs
• Multi-agent deployment with supervisor management (multiple agents per VM)
• Multi-region deployment across Azure regions
• Base64-encoded API keys for security
• Quota checking and public IP reuse support
• Clean cloud-init YAML generation with Python templating

Project reorganization:

• Moved AWS scripts into scripts/aws/ directory
• Moved Azure scripts into scripts/azure/ directory
• Updated all READMEs with multi-cloud documentation
• Updated .gitignore for cloud-init temp files

Pull Request Overview

This PR introduces comprehensive Azure deployment capabilities for NANDA agents alongside a significant project reorganization to support multi-cloud deployments. The changes enable deploying agents on Azure VMs with the same feature parity as existing AWS and GCP deployments, while reorganizing all cloud-specific scripts into dedicated platform directories for better maintainability.

Key changes:

• Added three Azure deployment scripts supporting single-agent, multi-agent, and multi-region deployments
• Reorganized AWS and GCP scripts into platform-specific subdirectories (scripts/aws/, scripts/gcp/)
• Updated all documentation to reflect multi-cloud architecture and provide platform-specific guidance

Things to improve:

API key security: ANTHROPIC_API_KEY is passed as a positional arg and written directly into cloud-init. Recommend supporting environment variables to avoid secrets appearing in shell history and process lists.

Firewall exposure: NSG rules allow traffic from all sources. Consider allowing configurable or restricted CIDRs.

Resilience: Agent is run with nohup and won’t auto-restart. Not blocking, but worth documenting.

Overall, this script is well-implemented and fits cleanly into the multi-cloud structure.
