- Remove pnpm-specific files (pnpm-lock.yaml, pnpm-workspace.yaml)
- Update package.json scripts to use npm instead of pnpm
- Add npm workspaces configuration
- Update all GitHub workflow files to use npm
- Update documentation to reference npm commands
- Generate package-lock.json for npm dependency management
