- Add .golangci.yml with v2 config (errcheck, govet, staticcheck, misspell, etc.) - Fix 32 errcheck issues across config, discord, ntfy, server packages - Fix misspelling: cancelled → canceled - Fix staticcheck: use append(slice...) instead of loop - Fix staticcheck: remove empty error branch - Use t.Setenv instead of os.Setenv/Unsetenv in tests - Update CI workflow: add lint job, release tagging, ntfy notifications
