- **Models**: add `Mimetype` model (mime_type.ts); add `SnakeCaseNamingStrategy` for User model
- **Validators**:
  - **updateDatasetValidator**: increase title length to 255 and description length to 2500
  - **User Validators**: refine `createUserValidator` and `updateUserValidator` to include `first_name` and `last_name`
- **vanilla_error_reporter**: improve error reporting for wildcard fields
- **SKOS Query**: refine keyword request in `SearchCategoryAutocomplete.vue`
- **UI Enhancements**:
  - improve icon design in wizard (Wizard.vue)
  - add components for mimetype creation (Create.vue and button in Index.vue)
- **Routes**: update `routes.ts` to include new AdonisJS routes
