Description

With ephemeral runners, the cache is often ineffective, so every job using Tailscale ends up downloading the binaries. Baking Tailscale into the runner image would avoid this, but the action always installs the package unconditionally.

It would be useful to have an option to skip installation and use the Tailscale binaries already present in the image.

Research direction

Start by locating the action's input definitions and the code that unconditionally installs Tailscale binaries. Trace how installation is invoked for a workflow, then review the existing tests and documentation around action inputs. Done means an option can use binaries already present in the runner image without downloading them, while the current installation behavior remains available.
