What's changed?

PR #5439 introduced logic to handle import ambiguity by using fully qualified names when conflicting usages are present. However, this led to regressions in cases where such conflicts only existed temporarily during multi-step recipe transformations.

Issue

When multiple recipes are applied, intermediate steps may introduce conflicting usages. But at the end might all such usage can be safely replaced to shortend names.

To handle this, updated AddImport to shorten existing fullyqualified names for the type or member for which import is being added.

Testing

Validated the fix by running all tests in the rewrite-testing-frameworks.
