コントラクト
- assert struct field named cause returns None from source() unless explicitly annotated with #[source]
- assert struct field named source implicitly enables source() without #[source]
- assert #[error(transparent)] forwards source() to inner error rather than returning inner as wrapper source
- assert #[from] error conversion silently loses call-site contextual parameters
- assert outer error formatting with {0} causes duplicate messages when walking source chain
