Research direction

Start with the reproduction in the issue and investigate rust-analyzer's rename handling for the thiserror #[error] attribute, comparing it with the mentioned serde(with) behavior. Done means renaming the source field also updates its usage in the attribute without breaking the generated error implementation.
