 * Boot-time API key validation for the plugin's `init` hook (node builds only).
 * Warns rather than throws when `OPENROUTER_API_KEY` is missing so the agent can
 * still start with limited functionality, and no-ops in browser environments
 * where the key lives behind the proxy. Also silences the AI SDK warning log
 * before any provider is constructed.
