## What would this feature solve? Users want to exclude certain files from being generated (e.g. test stubs, documentation files, or framework boilerplate). The generator supports an `.openapi-generator-ignore` file for this, but the plugin does not allow pointing to a custom ignore file or declaring ignore rules inline. ## Proposed Solution Add the following settings: - `ignoreFileOverride: String` — Path to a custom `.openapi-generator-ignore` file to use instead of the one in the output directory - `openapiGeneratorIgnoreList: List<String>` — Inline list of glob patterns to add to the ignore list without requiring a separate file These map to `CodegenConfigurator.setIgnoreFileOverride` and `setOpenapiGeneratorIgnoreList`. ## Which alternatives have been considered? Users can manually place a `.openapi-generator-ignore` file in the output directory, but that file is typically overwritten or managed by the generator and may not survive `cleanupOutput`. ## Additional Context Equivalent Gradle plugin properties: `ignoreFileOverride`, `openapiGeneratorIgnoreList`.
