perf(transformer/inject_global_variables): do not search string twice

[overlookmotel]

Small optimization. local.cow_replace('.', "_") searches the string and returns a Cow::Borrowed if it doesn't contain .. So use that result instead of an additional search with local.contains('.').

Walkthrough

The change updates the replace_name function within the InjectImport implementation. Instead of explicitly checking if the input string contains a dot (.), the function now uses the cow_replace method to replace all dots with underscores, resulting in a Cow<str>. The logic then checks the ownership of the result: if the replacement yields an owned String, it indicates that at least one replacement occurred, and the function returns a new formatted string prefixed with $inject_. If the result is a borrowed string, meaning no dots were present and no replacement was needed, the function returns None. The update also includes the addition of the std::borrow::Cow import to support this change. No modifications were made to the signatures of exported or public entities.
