Repo/CI hygiene batch (none base-affecting; image contents unchanged): - LICENSE: actual MIT file (repo previously declared MIT only in prose). - THIRD_PARTY.md: notes bundled software + licenses (pi/pi-fork/pi-obsmem/ pi-studio MIT, gosu Apache-2.0, Debian packages under their own terms). - .dockerignore: trims build context to what the Dockerfiles COPY (rootfs/ + entrypoint*.sh); keeps .git/docs/scripts/compose out. Verified it excludes none of the required COPY sources. - lint.yml: new hadolint job (pinned v2.14.0) lints both Dockerfiles; .hadolint.yaml grandfathers deliberate choices (DL3008/DL3016/DL4006/DL3003/ SC2086, mirroring the shellcheck excludes), fails on anything new at warning+. Verified hadolint exit 0 and the repo shell-guard passes with the new job. - IDEAS.md: parks deferred follow-ups (SHA-pin actions, trivy, buildx SBOM/ provenance, Makefile, renovate). - README/DOCKER_HUB License sections now link LICENSE + THIRD_PARTY.md. No tag.
