build: Dockerfile.backend multistage lint stage (closes #17 )

Dockerfile.backend did not follow the Go multistage lint-stage pattern
REPO_POLICIES.md mandates, and dragged the whole git history into the
build context to resolve a version string.

- Add an `AS lint` stage on the hash-pinned golangci/golangci-lint
  image (v2.7.2, the same golangci-lint commit main already pins), which
  ships Go, gofmt, make and the linter, so nothing is installed in it.
  It runs `make fmt-check` then `make lint`.
- Add `COPY --from=lint /src/go.sum /dev/null` to the build stage so
  BuildKit cannot run the two stages in parallel and let a lint failure
  through.
- Stop compiling golangci-lint from source in the build stage.
- Drop `COPY .git /repo/.git`; the version now comes from
  `ARG VERSION=dev`, passed to the build via `make build VERSION=...`.
- Drop gcc and musl-dev, and the corresponding
  `-linkmode external -extldflags -static` in backend/Makefile. The
  build is now `CGO_ENABLED=0 go build -trimpath` with
  `-ldflags "-s -w -X main.Version=... -X main.Buildarch=..."`, which is
  static without a C toolchain.
- backend/Makefile's VERSION is now overridable and degrades to `dev`
  when git or .git is unavailable instead of emitting a git error and
  building an empty version string.
- Every FROM stays pinned by @sha256 with a version and date comment.

Runtime stage, exposed port and entrypoint are unchanged.

Workflow

branch (from main)
do the work in Next Step
move Next Step to the top of Completed Steps
move the top item of Future Steps into Next Step
commit (TODO.md changes in the same commit as the work)
merge to main if the branch is not protected, otherwise open a PR
push

Status

pre-1.0. No git tags. Backend work in flight on feat/reportbuf-storage (dirty: src/main.js). Frontend is functional; backend is new and unmerged.

Next Step

Land feat/reportbuf-storage: finish the in-progress src/main.js change, get make check green, and merge the branch to main. The branch adds the backend (buffered zstd-compressed report storage), the CI workflow, and backend repo standard files, so merging it also closes most compliance gaps.

Completed Steps

2026-08-09: Dockerfile.backend reworked to the mandated Go multistage lint-stage pattern: separate lint stage on the hash-pinned golangci/golangci-lint image, COPY --from=lint stage dependency, CGO_ENABLED=0 static build driven by ARG VERSION, and no more COPY .git
2026-07-07 Adopted scripts-to-rule-them-all: script/ entrypoints, Makefile shims, README Entrypoints section
2026-02-27: backend with buffered zstd-compressed report storage; CI workflow and backend repo standard files; backend Dockerfile fixed (Go 1.25, golangci-lint) and moved to repo root (feat/reportbuf-storage, unmerged)
2026-02-26: host row layout redesigned with CSS grid; overflow and spacing fixes; nginx config extracted; port hardcoded to 8080
2026-02-26: debug log panel, median stats, recovery probe, Docker build fix, S3 Singapore endpoint added
2026-02-23: summary box redesign, host pinning, local and UTC clocks, checks counter
2026-02-23: hosts sorted by latency; GET instead of HEAD for latency; timeout derived from interval; Hetzner regional endpoints; 3s interval
2026-01-29: initial NetWatch network latency monitor

Future Steps

Compliance top-up as one small commit: add .editorconfig and add the hooks target to the Makefile
After merge, confirm .gitea/workflows/check.yml is on main and CI is green (main always green policy)
Decide what to do with untracked resume.sh: commit it, gitignore it, or delete it
