Enforces unit test requirements for the Rust data-processing modules in src-tauri/src/sql/ (generator.rs, parse.rs) and src-tauri/src/reader/ (excel.rs and other readers). Use when writing, editing, or reviewing Rust code in these modules. Ensures stability tests (and performance tests for hot-path code) are added for any change, and that tests follow the shared `<module>_test.rs` convention.

Enforces strict avoidance of unwrap() in Rust code. Use when writing, editing, or reviewing Rust (.rs) code in this project. Prevents unsafe panic-prone patterns and promotes proper error handling alternatives.
