fix(es/hygiene): Ignore eval in default hygiene pass (#12003) **Description:** Fixes hygiene renaming when transformed code contains direct `eval`. Previously, the default hygiene pass treated `eval`/`with` as a reason to avoid renaming user-written bindings. That left SWC in an unsafe middle state for ES5 transforms: block-scoped bindings could be lowered to `var`, but conflicting names would not be renamed afterward, causing scope collisions. This PR keeps `Config::default()` conservative, and adds `Config::hygiene_default()` for SWC’s normal correctness hygiene behavior. The default `hygiene()` pass now uses that config, so it still resolves identifier conflicts even when `eval` is present. Minifier name mangling remains controlled separately by `mangle.eval`. Also adds a regression fixture for #9791, ensuring the inner `show_type` binding is renamed while the later `eval`-containing callback still reads the outer `show_type`. Validation run: - `cargo fmt --all` - `cargo clippy --all --all-targets -- -D warnings` - `cargo test -p swc 9791 --test projects` - `cargo test -p swc_ecma_transforms_base hygiene --lib` **BREAKING CHANGE:** None. **Related issue:** - Closes: #9791 - Closes: #12001 - Closes: #12002
