check / check (push) Failing after 1s
Add the standard scaffold and bring the tree to a clean lint under the vendored `default: all` config. New: `script/` Scripts-to-Rule-Them-All entrypoints with the `Makefile` reduced to thin shims; a `Dockerfile` whose `lint` and `test` phases gate the build (final stage depends on both); a `.gitea/workflows/` CI running `script/cibuild`; the vendored `.golangci.yml`; `REPO_POLICIES.md`; `.editorconfig`; `.dockerignore`; a `LICENSE` (WTFPL) and `TODO.md`; and a comprehensive `.gitignore`. The 211 lint findings were fixed, not suppressed: package-level state became functions/fields/a command constructor, magic numbers became named constants, `ctx` is threaded into the probes, the loop functions were split to cut complexity, and the deprecated `+build` tags were dropped. Behavior is unchanged. The only annotations are justified `//nolint:gosec` on the `ping`/`curl` subprocess calls (G204, fixed argv) and the operator-chosen log file (G304), matching the reference repos. `make check` is green (lint and tests run in Docker).
