build: re-vendor canonical files from prompts dd4027b (closes #257)
The canonical files are fetched whole from sneak/prompts at dd4027b.
Kept after the canonical content: the livednstest deny entry in
.golangci.yml, /bin in .dockerignore, this repo's own .gitignore lines
and a [*.go] tab section in .editorconfig. The workflow keeps its
concurrency block and persist-credentials: false. Lint and test are
phases of the Dockerfile (golangci-lint v2.14.0; tests on the Debian
Go 1.25.7 image as an ordinary user, with the same flags); the build
stage depends on both and stamps the version the canonical way.
Dockerfile.lint is gone; the prettier stages of Dockerfile.fmt moved
into the Dockerfile. Every scripted docker build passes --no-cache;
script/cibuild bootstraps, runs script/check, then builds the image.
script/fmt-check absorbs fmt-check-go and fmt-check-markdown.

# script/bootstrap: install all dependencies needed to build and develop
# this repo. Idempotent: every install is guarded by a check so already
# installed tools are skipped. Base tooling comes from nix, apt, brew,
# or apk (detected in that order); assumes nothing is present.
# goimports is not installed here: script/fmt and script/fmt-check run
# it with `go run` at a pinned commit.
# The linter is NOT installed here: golangci-lint runs via docker only
# (script/lint), pinned by image digest, so its only prerequisite is a
# working docker. Nor is prettier: script/fmt and script/fmt-check run
# it in a stage of the Dockerfile.
