Pull request overview

This PR updates the project’s Go/tooling setup to run the metrics tracker test under the synctest GOEXPERIMENT, while also aligning the repository’s Go version and module dependencies (notably OpenTelemetry and x/net) to the chosen toolchain.

Changes:

• Gate tracker/metrics/tracker_test.go behind //go:build goexperiment.synctest and switch to synctest.Run(...).
• Run the test suite with GOEXPERIMENT=synctest via make test.
• Align build/toolchain inputs by updating go.mod/go.sum dependency versions and the Docker builder image Go version.
