 ### 2025-06-28 - Increment 6: Implement CLI Argument Parsing and Execution
 *   **Description:** Integrated the `unilang` core into a basic CLI application (`src/bin/unilang_cli.rs`). Implemented a `main` function to initialize `CommandRegistry`, register sample commands, parse command-line arguments, and use `Lexer`, `Parser`, `SemanticAnalyzer`, and `Interpreter` for execution. Handled errors by printing to `stderr` and exiting with a non-zero status code. Corrected `CommandDefinition` and `ArgumentDefinition` `former` usage. Implemented `as_integer` and `as_path` helper methods on `Value` in `src/types.rs`. Updated `CommandRoutine` signatures and return types in `src/bin/unilang_cli.rs` to align with `Result<OutputData, ErrorData>`. Corrected `Parser`, `SemanticAnalyzer`, and `Interpreter` instantiation and usage. Updated `cli_integration_test.rs` to match new `stderr` output format. Removed unused `std::path::PathBuf` import. Addressed Clippy lints (`unnecessary_wraps`, `needless_pass_by_value`, `uninlined_format_args`).
 *   **Verification:** All tests passed, including `cli_integration_test.rs`, and `cargo clippy -p unilang -- -D warnings` passed.
-*   [2025-07-23] fix(unilang): Resolved compilation error in `unilang_cli.rs` by correcting the parser method and argument type.
