Remove GitHub Actions ecosystem from Dependabot and delegate CI to reusable workflow

Removes GitHub Actions package ecosystem monitoring from Dependabot configuration. Replaces inline Go CI job (checkout, setup, OpenBLAS install, tidy, build, test) with call to centralized reusable workflow at qntx/workflows. Renames workflow from "Go" to "Go CI" and removes workflow_dispatch trigger.
