Skip README generation when package installation is skipped

When --skip-install is used, the package is not installed, so commands won't be loaded. This would cause package-readme to fail with the missing commands error. Instead, we now skip README generation with a warning message explaining that commands must be loaded for complete documentation.

Users who want to skip installation but still generate a README can manually run 'wp scaffold package-readme' after ensuring commands are loaded via wp-cli.yml or package installation.
