Bring the repo up to the standard layout (closes #1)

Adds the canonical .gitignore, .dockerignore and .editorconfig; the
first two also name this repo's build output, root-anchored so
cmd/bsdaily/ stays in. The Dockerfile gains a lint phase on the
golangci-lint image already pinned and a test phase on the Debian Go
image with sqlite3 and zstd; the build stage copies a file from each,
so a plain docker build cannot skip them. script/lint and script/test
build their phase uncached and tagged; script/cibuild, script/docker
and the CI workflow are the canonical copies. Nothing installs
golangci-lint on the host. REPO_POLICIES.md is re-vendored.

.golangci.yml and the lint cleanup: #6
Judgement call: .gitignore adds Go build output, per the Go styleguide.

Model: opus-5-5
