Adds a fourth visibility tier alongside private/unlisted/public: "followers" — visible to the author and anyone who follows them, excluded from public search/explore/profile listings and from the anonymous /r/[id] share route, included in the Following feed. The in-app recipe detail gate and the public share route both check follow status directly against the DB rather than the union type alone, since neither previously had any per-viewer access logic for a non-public/non-owner case. Requires the generated migration (0041) to run against a live DB — not applied in this sandbox (no Docker here); run `pnpm db:migrate`. v0.41.0
