The publisher's own command. Not a PlugMCP endpoint.

- THREE_WS_API_KEY — A three.ws API key (sk_live_… / sk_test_…) with the herald:announce scope, or an OAuth access token for the same account, carried as Authorization: Bearer. Required: an announcement is always delivered to the key owner's own sessions. Aliases: THREE_WS_TOKEN, THREE_WS_BEARER. Treat like a password.
- THREE_WS_BASE — Base URL of the three.ws API. Override only when self-hosting or targeting a preview deployment.
- THREE_WS_TIMEOUT_MS — Per-request timeout in milliseconds for the announce call.
