 - `checkImportedTypes` ... Controls whether to check properties from types defined in external files. Default is `false`, meaning the rule only checks types defined within the component file itself. When set to `true`, the rule will also check properties from imported and extended types.
 - `ignoreTypePatterns` ... Regular expression patterns for type names to exclude from checks. Default is `[]` (no exclusions). Most useful when `checkImportedTypes` is `true`, allowing you to exclude specific imported types (like utility types or third-party types) from being checked.
 - `ignorePropertyPatterns` ... Regular expression patterns for property names to exclude from unused checks. Default is `[]` (no exclusions). Most useful when `checkImportedTypes` is `true`, allowing you to ignore specific properties from external types that shouldn't trigger warnings.
