chore: update biome config and enforce separated type imports

- Fix biome.json $schema to point to correct configuration schema
- Add .turbo to ignored directories
- Add linter rules: noBarrelFile, useImportType (separatedType style)
- Reorganize import sorting groups to separate type and value imports
- Enable JSON comment parsing and explicit JS formatter
- Reorder imports across src/ and tests/ to match new style rules
