feat: GCP multi-cloud deployment with 100-agent configurations

[rahul240699]

GCP deployment features:

• Single agent deployment script for GCP Compute Engine
• Multi-agent deployment with supervisor management (multiple agents per VM)
• Multi-region deployment across GCP zones
• Firewall rules auto-configuration
• Metadata service integration

Agent configurations:

• 100-agents-flat-unique.json: Unique agent IDs across all domains (ports 6000-15000)
• 100-agents-flat.json: Simplified flat structure for testing
• 100-agents-config-clean.json: Clean configuration format

Project reorganization:

• Moved AWS scripts into scripts/aws/ directory
• Added GCP scripts in scripts/gcp/ directory
• Updated all READMEs with multi-cloud documentation
• Updated .gitignore for temporary files

Pull Request Overview

This PR introduces comprehensive GCP multi-cloud deployment capabilities alongside extensive agent configuration support. It enables deploying NANDA agents across both AWS and GCP with flexible single-agent, multi-agent, and multi-region deployment options, supported by three 100-agent configuration files for various deployment scenarios.

Key Changes:

• GCP deployment infrastructure with single-agent, multi-agent, and multi-region deployment scripts
• Three 100-agent configuration files (flat, flat-unique, and clean) with ports spanning 6000-15000
• Project reorganization with dedicated aws/ and gcp/ directories and comprehensive platform-specific documentation

This PR is a strong, well-structured addition that introduces full GCP support, including single-agent, multi-agent, and multi-region deployment scripts, while reorganizing existing cloud scripts and expanding documentation. All changes are isolated to the scripts/ directory, with no modifications to core NEST code, which keeps the PR low-risk and easy to integrate.

The GCP scripts follow the same patterns as the AWS and DigitalOcean equivalents, with solid use of metadata services, firewall setup, supervisor for multi-agent deployments, and clear logging and validation. The three new agent configuration files are useful for large-scale or load-testing scenarios; the two 100-agent configs are valid and well-structured.

One point to revisit: 100-agents-config-clean.json appears to be a template, not a real 100-agent config (it contains ~10 agents and repeats IDs). Renaming it or clarifying its purpose would avoid confusion.

Overall, this PR significantly improves NEST’s multi-cloud deployment readiness and is well-organized and easy to review. I recommend approving with the minor naming clarification mentioned above.
