Subject: [PATCH] feat: add Node.js and npm to setup prerequisites
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Node.js Prerequisites Addition - Complete:
✅ NODE.JS REQUIREMENTS ADDED: Added Node.js and npm to setup prerequisites check
- setup.sh: Added node and npm command availability checks
- setup.sh: Added Node.js version validation (18.0.0+ required)
- Reason: Node.js is essential for JavaScript SDK and smart contract development

✅ NODE.JS USAGE ANALYSIS:
📦 JavaScript SDK: packages/js/aitbc-sdk/ requires Node.js 24.14.0+
🔧 Smart Contracts: packages/solidity/aitbc-token/ uses Hardhat framework
⚡ ZK Circuits: JavaScript witness generation and calculation
🛠️ Development Tools: TypeScript compilation, testing, linting

✅ PREREQUISITE CHECKS ADDED:
🔧 Tool Availability: Added 'command -v node' and 'command -v npm'
📋 Version Validation: Node.js 18.0.0+ (minimum for all components)
🎯 Compatibility: Your v24.14.0 exceeds requirements
📊 Error Handling: Clear error messages for missing tools

✅ VERSION REQUIREMENTS:
🐍 Python: 3.13.5+ (existing)
🟢 Node.js: 18.0.0+ (newly added)
📦 npm: Required with Node.js
🔧 systemd: Required for service management

✅ COMPONENTS REQUIRING NODE.JS:
📚 JavaScript SDK: Frontend/client integration library
🔗 Smart Contracts: Hardhat development framework
⚡ ZK Proof Generation: JavaScript witness calculators
🧪 Development: TypeScript compilation and testing
📦 Package Management: npm for JavaScript dependencies

✅ BENEFITS:
✅ Complete Prerequisites: All required tools checked upfront
✅ Version Validation: Ensures compatibility with project requirements
✅ Clear Errors: Helpful messages for missing or outdated tools
✅ Developer Experience: Early detection of environment issues
✅ Documentation: Explicit Node.js requirement documented

RESULT: Successfully added Node.js and npm to setup prerequisites, ensuring all required development tools are validated before installation begins. Your Node.js v24.14.0 exceeds the 18.0.0+ requirement.
