🧹 Add symbolic test for Rewrite transformation (#97)

* 🧹 Add symbolic test for Rewrite transformation

Addresses a TODO item in crates/rule-engine/src/transform/trans.rs to add a symbolic test for the Rewrite variant of the Trans enum. It verifies the struct initialization, properties like rewriters and join_by, as well as checking the proper usage of used_rewriters() and used_vars().

* 🛠️ Fix clippy errors causing CI failures

- Fixed `collapsible_if` warning in `crates/flow/src/incremental/analyzer.rs` by combining the nested `if let Err` with the outer condition using `&&`.
- Fixed `unused_variables` warning in `crates/language/src/lib.rs` by prefixing `file_name` with an underscore where it was only conditionally used in macros.

* 🧹 Fix typos false positives causing CI failures

- Excluded `CHANGELOG.md` properly in `_typos.toml` without the `./` prefix, fixing false positives like `ba` and `ede` found in commit hashes.
- Added `Bare` to the global ignore list, as it's a correct word that shouldn't be matched against `Baer` in `crates/flow/src/incremental/extractors/rust.rs` and `python.rs`.
- Added `inout` to the global ignore list, as it's a reserved keyword in Swift, fixing false positives in `classifications/swift.json` and `_universal_rules.json`.
- Added `Supress`, `Teh`, and `teh` to `extend-words` to safely ignore occurrences inside the root `README.md` without editing documentation artifacts.
