 * Read the host's own `openai` OAuth credential from OpenCode's auth store.

 * The plugin backfills that entry from the account pool (see
 * `backfillHostOpenAIAuthFromPool` in index.ts) and the host refreshes its
 * copy independently — so it can serve requests entirely outside pool
 * rotation, including while every pool account is disabled. Diagnostics
 * surface its presence so "traffic works but the pool says disabled" is
 * explainable instead of a paradox (#288).
