lora-executor 0.11.0

//! Regression baseline for `ExecutorError` `Display` output.
//!
//! These messages flow out through `LoraError::message()` and end
//! up in user-visible exceptions on the binding side. Pinning each
//! variant catches wording drift before it changes user-visible
//! behaviour.
