diktat Parser - Kotlin style and quality checker integration.

diktat is an opinionated, no-setup, Kotlin static analysis tool with built-in
code formatter. It provides an alternative to detekt with different rule sets
and formatting capabilities.

diktat provides:
- Style checking with built-in formatter
- Configurability via YAML
- Custom rule creation support
- Gradle plugin integration
- JSON report output
