Upgrade project to Node.js 18

[Copilot]

This PR upgrades the green-webhook project from Node.js 14-16 to Node.js 18, ensuring compatibility with the latest LTS version and improving security and performance.

Changes Made

• Updated .nvmrc: Changed from lts/* to 18 to specify Node.js 18 explicitly
• Updated package.json: Modified engines constraint from >=14.19 <=16.x to >=18.0.0 <19.0.0

Compatibility Testing

The upgrade has been thoroughly tested with Node.js 18.20.8:

✅ Core Functionality

• RedwoodJS v3.3.1 works perfectly with Node.js 18
• All CLI commands (yarn rw info, yarn rw lint) function correctly
• Package dependencies install without version conflicts
• Modern JavaScript features (optional chaining, nullish coalescing) confirmed working

✅ Development Environment

• ESLint and TypeScript compilation work seamlessly
• Yarn 3.2.3 package manager fully compatible
• Development server starts successfully (API on port 8911, web builds complete)
• Webpack 5.74.0 builds React application without issues

✅ Runtime Testing

• API server built and started successfully using Fastify
• Web application builds and bundles correctly
• No breaking changes to existing codebase
• All existing dependencies remain compatible

Benefits

• Security: Node.js 18 includes latest security patches and improvements
• Performance: Better V8 engine performance and memory management
• Future-proofing: Aligns with current LTS version for long-term support
• Modern features: Access to latest JavaScript and Node.js APIs

Migration Notes

This is a non-breaking upgrade that requires no code changes. The existing codebase works seamlessly with Node.js 18. Developers should update their local Node.js version to 18.x when working on this project.

To use the new version locally:

nvm use  # Will automatically use Node.js 18 based on .nvmrc

This pull request was created as a result of the following prompt from Copilot chat.

The project green-webhook needs to be upgraded to use Node.js version 18. This involves updating the relevant configuration files such as package.json or .nvmrc, ensuring compatibility with Node.js 18, and testing the application to confirm it functions correctly with the new version. If there are dependencies that are incompatible with Node.js 18, they should also be updated to compatible versions.
