 path utilities

- Added maxdepth and mindepth parameters to find function for depth-controlled file search.
- Added counter function to count occurrences and sort by frequency.
- Added basenames function to extract base names from paths.
- Fixed biome.json configuration to remove invalid double negation pattern.
