/**
 * Test-connection probe for Voyage AI embeddings API.
 *
 * Makes a small real embedding call against
 *   POST https://api.voyageai.com/v1/embeddings
 * with the configured model (voyage-3) and a fixed test input. Returns
 * `ok: true` on HTTP 200, `ok: false` on auth / network / other errors.
 *
 * The probe never echoes the upstream error body — only a generic
 * canned phrase and the HTTP status code (no headers, no payload).
