.gitignore had docs/* blocking everything; the rest of the directory
remains user-local notes, so whitelist only the two files that belong
to the project: improvements.md (Arch-ification roadmap, with the
architectural decision that LibreELEC overlay is by design) and
release-policy.md (semver-RC until v2.0, YYYY.MM.PATCH after, three
release channels mapped to updates.branch).
