ethora-agents-activate-v2
Bind a saved agent as the active AI bot for the current app — copies the agent's config onto the app's bot, replacing whatever was there before (POST /v2/agents/:agentId/activate). Does not by itself set status: "on" — pair with ethora-bot-enable-v2 if needed.
Auth: app-token mode (after ethora-app-select + ethora-auth-use-app). Errors: 401/403 wrong auth; 404 agentId not an agent of the current app. Related: verify with ethora-bot-get-v2.
