Code Review

This pull request enables generation for the Google Storage Control v2 library and updates the npm installation command in librarian.js to use a specific cache directory and suppress audit/funding messages. The reviewer suggests avoiding the hardcoded /tmp/npm-cache path to prevent permission conflicts on shared build agents and ensure cross-platform compatibility, recommending a cache directory within the package root instead.

[gemini-code-assist]

Hardcoding /tmp/npm-cache can cause permission conflicts on shared build agents (e.g., if different builds run under different users) and is not cross-platform. Consider using a directory within the package root to ensure a safe, isolated, and cross-platform cache location.

Suggested change

	execSync('npm install --cache=/tmp/npm-cache --no-audit --no-fund', {cwd: packageRoot, stdio: 'inherit'});
	execSync('npm install --cache=' + path.join(packageRoot, '.npm-cache') + ' --no-audit --no-fund', {cwd: packageRoot, stdio: 'inherit'});
