RootBuilder class

Root builder that provides entry points for different data types.

Usage Examples:

// String validation
final nameValidator = v().string().lengthMin(2).lengthMax(100).build();

// Number validation with coercion
final ageValidator = v().string().toInt().gte(0).lte(150).build();

// Complex object validation
final userValidator = v().map().schema({
  'name': v().string().lengthMin(1).build(),
  'email': v().string().email().build(),
  'age': v().int_().gte(18).build(),
}).build();

// List validation
final tagsValidator = v().list().each(v().string().lengthMin(1).build()).build();
