golangci-lint v2 ignores a top-level linters-settings block without a
warning, so limits such as the 88-column line length were never
applied. .golangci.yml is now the canonical copy from sneak/prompts,
verbatim, which keeps its settings under linters.settings and also
configures depguard and gomodguard_v2. golangci-lint is pinned at
v2.12.2 by commit in the Dockerfile and script/bootstrap. The long
lines in attrsum.go are rewrapped and one nolint directive moves to
its own line; behaviour is unchanged.

`make try` ran against a fixed directory on one person's machine. It
failed for anyone else, and where that directory existed it rewrote the
checksum attributes and modification times of real files.
It now writes three small files into a new directory from `mktemp -d`,
runs the same sequence of commands on it, and removes it with an EXIT
trap. All steps run in one shell, so the trap also removes the
directory when a step fails.
`TODO.md`: the `try` sentence leaves Next Step and is recorded under
Completed Steps.

attrsum --version now prints the git tag or short commit. make build
stamps it with -X from git describe, and the Dockerfile takes the VERSION
build argument when given, otherwise git describe --tags --always on the
.git in the build context, failing if .git is present and no version
comes out. A new .dockerignore, the canonical one, keeps .git/config out
of the context, and also this repo's host-built /attrsum. CI checks out
full history so it sees the 1.0.0 tag and stamps what a full clone does.
script/docker is replaced with the canonical copy.
