## Motivation Close #93415 ## Summary Separate `@available` attributes for the same platform are accepted in source, but interface emission combines them into an invalid attribute with duplicate platform entries. Coalesce short-form availability attributes by domain, retaining the greatest introduction version and preserving platform order. This supports combining a shared availability macro such as `MyLib_v1_0` with a stricter requirement on one platform. ## Test Add regression coverage for the macro case in both attribute orders, repeated versions, long and mixed forms, overlapping platform groups, platform aliases, and preservation of deprecation information.
