Pull request overview
This pull request enhances the generic type normalization logic to properly preserve pointer types in generic iterators, specifically addressing the need to handle types like iter.Seq2[*github.Artifact, error] where pointer prefixes must be maintained.
Changes:
- Refactored normalizedGenericTypeName to handle multiple type parameters and extract pointer handling into a separate helper function
- Added normalizeFullTypeName helper function to normalize individual type names while preserving pointer prefixes
- Added comprehensive unit tests covering various generic type scenarios including pointers, multiple type parameters, and versioned imports

The regex pattern is compiled on every function call. Since this function may be called multiple times during code generation (once per type parameter), consider moving the regex compilation to a package-level variable to improve performance. For example, declare var versionPattern = regexp.MustCompile(\/v\d+\.`)` at the package level and reuse it in this function.

Potential index out of bounds error. The code assumes that when versionPattern matches, parts[len(parts)-1] (the last path segment) will contain a dot and can be safely split to access index [1]. While this is true for well-formed versioned import paths like armappconfiguration/v2.ConfigurationStoresClientListResponse, malformed input could cause a panic. Consider adding a bounds check or using a more defensive approach, such as checking the length of the split result before accessing index [1].
