+//! Vendor image tag resolution (studio#128): resolves a vendor name (e.g.
+//! `claude`, `codex`, `cursor`, `kiro`, `antigravity`) to real,
+//! currently-published `ghcr.io/openabdev/openab` image tags — "Beta" (the
+//! hourly rolling `pre-beta-<vendor>` build) and "Stable" (the newest
+//! openab release whose matching `<version>-<vendor>` image is confirmed to
+//! actually exist).
+//!
+//! A GitHub release tag existing does **not** guarantee a matching image

+//! manual `workflow_dispatch` step, completely disconnected from cutting a
+//! release — confirmed by reading both workflows. So "stable" has to be
+//! verified against GHCR directly, not inferred from the release list
+//! alone.
+//!
+//! All access here is anonymous — no GitHub token needed. `ghcr.io` speaks
+//! the standard OCI Distribution API, and `openabdev/openab` is a public
+//! package: `GET /token?scope=repository:<repo>:pull` mints a scoped
+//! anonymous pull token, the same flow `docker pull` uses against a public
+//! image with no login. This is a different API from GitHub's Packages
+//! REST API (`/orgs/.../packages/...`), which *does* require a
+//! `read:packages`-scoped token even for public packages — deliberately
+//! not used here for that reason.
