Keeping Clay up to date

The plugin bundles and pins a specific clay CLI version. Because of that pin, clay update cannot self-update here: it detects the plugin-managed binary and tells you to update the plugin instead. So for plugin users, "update the CLI" means update the plugin — that moves the pin, and the newer CLI is fetched on next use.

1. Check what you're on, and whether a newer version exists

clay --version        # reports <cliVersion>+<commit>
clay update --check   # reports { updated, latestVersion, message }

clay update --check reports the latest published CLI version and a message. In the plugin, that message is:

"This binary is managed by the Clay agent plugin and is pinned to a specific version. Update the plugin to change the CLI version."
