name: "Set up uv with retries"
description: >-
  Install uv via astral-sh/setup-uv, retrying on transient failures. Even with
  an exact pinned version, the action resolves the artifact URL by fetching
  https://raw.githubusercontent.com/astral-sh/versions/main/v1/uv.ndjson in a
  single request with no retry, timeout, or fallback, so one connection-level
  network error ("fetch failed") fails the whole job before any test runs.
  Retrying the full step covers the manifest fetch and the binary download.
