Get the currently authenticated LinkedIn user's profile: name, email, person URN, and profile picture URL. Use this to confirm who is logged in or to retrieve the user's identity. Requires prior authentication.

Log out of LinkedIn by deleting the stored OAuth token. Use when the user wants to switch accounts or revoke access. After logout, linkedin_auth must be called again before using any other tools.
