Function error_to_validation_error 

pub fn error_to_validation_error(error: Error) -> ValidationError

Collapse a runtime Error into the ValidationError the Validate trait returns.

Error::Validation passes through unchanged. Error::Compilation and Error::Runtime cannot be represented by the trait’s return type, so they surface as a single synthesized Violation carrying the error’s cause (empty rule_id) rather than silently succeeding — the same known-limitation class as bytes.pattern on invalid UTF-8 in the compile-time path. Callers needing to distinguish these should use RuntimeBridge::validate_wire directly.
