It sets up Python, installs `uv`, then installs `mergify-cli` (pinned by default,
7-
`latest` supported) and exposes the resolved version as an output.
6+
It installs the prebuilt `mergify` binary via the mergify-cli `install.sh`
7+
installer, which downloads the binary from the GitHub release and verifies it
8+
against the release `SHA256SUMS`. For a pinned version the installer is fetched
9+
from that release tag; `latest` uses `main`. The action then puts the binary on
10+
`PATH` and exposes the installed version as an output. Pinned by default,
11+
`latest` supported. No Python or toolchain is required; Linux and macOS are
12+
supported.
