## Summary `unionCapabilities` merges `Experimental` map entries from inner variant servers but skips the `Extensions` field entirely. This means any extension registered via `ServerCapabilities.AddExtension()` on an inner server (e.g. `io.modelcontextprotocol/skills`) is silently dropped from the front proxy's `InitializeResult`. - Add the same first-wins merge logic for `Extensions` that already exists for `Experimental` - Bump `go-sdk` to v1.4.1 which introduced the `Extensions` field on `ServerCapabilities` - Add unit test for `unionCapabilities` extensions merging - Add integration test verifying extensions survive the variant path end-to-end ## Test plan - [x] `TestUnionCapabilities_MergesExtensions` — verifies first-wins merge semantics for extensions - [x] `TestIntegration_ExtensionsAdvertised` — verifies extensions registered on inner servers appear in the client's `InitializeResult` - [x] All existing tests pass (27/27) Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
