Pull Request Overview

This PR migrates npm configuration from .npmrc files to package.json config sections across the VS Code repository. The primary motivation is to consolidate build configuration into standard package.json format, replacing scattered .npmrc files with centralized config sections.

Key changes:

• Replaces .npmrc configuration files with config sections in package.json files for node-gyp settings
• Updates all code that parsed .npmrc files to instead read from package.json config sections
• Removes .npmrc files from 40+ locations across the codebase (root, build, remote, extensions, and test directories)
• Updates Node.js and npm version requirements (Node.js > v24.11.0 or >= v25.0.0, npm >= 11.6.2)

Potential null reference error: process.env.npm_config_npm_version may be undefined, causing exec() to return null. This will cause a crash when accessing npmVersion[1] on line 11. Add null checking or provide a fallback value.
