fix: make directory exclusion case-insensitive for cross-platform compatibility

  The shouldProcessFile function used case-sensitive path comparisons, which
  could fail to exclude directories like NODE_MODULES or Node_Modules on
  case-insensitive file systems (Windows/macOS).

  - Convert file paths to lowercase before pattern matching
  - Update tests to verify case-insensitive behavior
  - Ensures consistent directory exclusion across all platforms
