Pull request overview

This PR adds the n/global-require linter rule from eslint-plugin-n, which enforces that require() calls are placed at top-level module scope. This helps improve code clarity by making dependencies easier to identify and prevents potential performance issues from synchronous loading within functions or conditional statements.

Key Changes:

• Implements the GlobalRequire rule that detects require() calls not at module scope
• Adds comprehensive test cases covering various invalid patterns (functions, conditionals, try-catch, arrow functions)
• Properly handles shadowed require identifiers to avoid false positives

The error message should include a help message to guide users on how to fix the issue. Consider adding .with_help("Move require() to top-level module scope") to make the diagnostic more actionable, similar to how other node rules provide help messages.
