refactor: update import paths to the new repository location

Change the import paths in CLAUDE.md and go.mod to reflect the
migration of the otelsetup module from GitLab to a new Git server.
Remove the build status and code coverage badges from README.md as
they are no longer applicable. Update configuration in
.pre-commit-config.yaml to match the new module path.
