Subject: [PATCH] fix(@angular/build): invalidate cached SCSS errors when
 source files are corrected

Normalize the file path before looking it up in the dependency map
during cache invalidation. Without normalization, the path used for
invalidation could differ from the one stored during compilation,
causing stale error results to persist after fixing SCSS errors.

Fixes #32744
