This callback is invoked during schema generation to conditionally ignore properties
based on the current context and the default ignore value.

### Usage

const ignoreCallback: IgnoreCallback = (value, ctx) => {
  // Ignore properties when specific groups are active
  if (ctx.groups?.includes('admin')) {
    return false; // Don't ignore for admin group

  return value; // Use default ignore value
};
