Summary

• Update the MyGo replacement from 5c865d27d866 to merged main 7fe2886ceea77692e60bbb2efbb8c184e6e15cdb and regenerate its two checksums. The existing pin remains valid and already includes Add Qt/QML backend (platform/qt) #21/apple: render LUI elements with iOS-native idioms by default #22; this adds child-first arrow routing, committed clipped layout widths and the Darwin global-language fix.
• Keep the upstream module/import identity and every other dependency unchanged. The new navigation/layout APIs remain opt-in; this does not wire new LUI behavior. Embedding applications must update their own MyGo replacement independently because Go does not inherit dependency replacements.

Validation with GOWORK=off and GOTOOLCHAIN=local: module verification and exact replacement resolution, ./tooling/test_mygo.sh --unit (schema freshness, 24 Python tests, allocation checks and full Go race suite), go vet ./..., macOS build and cgo-free Linux/Windows amd64 cross-builds passed. No new tests, SDK/API/protocol changes, native application integration run or GUI acceptance.
