/**
 * Migration — create the empty `rfq_outbound` PocketBase collection.
 *
 * RFQ-by-email is v2's "Send to supplier and let them reply" loop.
 * This migration creates the table now (zero rows, zero behaviour
 * in v1) so the schema is ready when v2 lands — no retrofit, no
 * migration-with-data-backfill.
 *
 * One row per outbound RFQ email we sent on a quote_item. When the
 * supplier replies, the existing inbound email monitor drops a row
 * into `quote_replies` as today; a v2 branch in the Switch (or a
 * new workflow) also resolves the In-Reply-To header back to an
 * rfq_outbound row and links the response to the same item.
 *
 * Fields (deliberately lean — we can extend when v2 is real):
 *
 *   - quote_item      relation → quote_items
 *   - supplier        relation → suppliers (resolved from the
 *                       price_list row we matched against, or the
 *                       operator's override)
 *   - email_subject   text
 *   - email_body      text
 *   - email_message_id text  (Message-ID header we set when
 *                              sending — used for In-Reply-To
 *                              resolution when the supplier replies)
 *   - sent_at         date
 *   - status          text   pending | replied | expired | no_reply
 *   - raw_email_id    text   (optional — the raw SMTP / n8n
 *                              delivery id for audit)
 *
 * Idempotent — re-runs skip silently if the collection already
 * exists.
 *
 * Run with:
 *   npx tsx scripts/migrations/2026-06-30-create-rfq-outbound.ts
