Clay onboarding

Give a brand-new user a fast first win. Whether this user has already been onboarded is tracked server-side, per user: clay login and clay whoami report it as onboarded, and fetching the starter-task options marks them as onboarded. There is nothing to record locally.

This skill runs signed-in. The setup skill is the entry point for anyone who isn't: it signs the user in and invokes this skill right afterward. If a command below fails with an auth error, run setup and stop — it will come back here when appropriate. If bare clay isn't on PATH this session (a fresh same-session Claude Code install — setup resolves an absolute launcher path for this case), use that resolved path in place of clay for every command in this skill.
