Subject: [PATCH] fix: require fileutils for OpenApiImport.from (v0.12.1)

Avoid uninitialized constant when the gem is required without another
stdlib dependency loading FileUtils first. Bump to 0.12.1 and add a
regression spec.

+## [0.12.1] - 2026-03-24
+
+### Fixed
+- Require `fileutils` from the gem entrypoint and call `::FileUtils.rm_f` so `OpenApiImport.from` does not raise `uninitialized constant OpenApiImport::FileUtils` when nothing else has loaded the stdlib first
+
 ## [0.12.0] - 2026-03-17
 
 ### Added
