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

Vendors .gitignore, .dockerignore, .editorconfig, REPO_POLICIES.md,
script/cibuild, script/docker, script/lint, script/test and the CI
workflow byte-identical from sneak/prompts commit cc440118c876; the
two ignore files then add this repo's own 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. Nothing installs
golangci-lint on the host. On apt, script/bootstrap refreshes the
package lists once before its first install.
