+ * One-shot migration: fields for the AI order assistant.

+ *   orders.ai_quote_match                          json  (per-order AI verdict)
+ *   order_items.ai_fill                            json  (per-line fill record)
+ *   ai_settings.order_assistant_enabled            bool
+ *   ai_settings.order_assistant_interval_minutes   number
+ *   ai_settings.order_assistant_auto_link          bool
+ *   ai_settings.order_assistant_fill_lines         bool
+ *   ai_settings.order_assistant_prompt             text  (max 50000)
+ *   ai_settings.order_assistant_last_run_at        text  (max 40)
+ *   ai_settings.order_assistant_last_run_summary   json
+ *
+ * Run with:
+ *
+ *     npm run pb:migrate:order-assistant
+ *
+ * Idempotent — fields that already exist are skipped. Manual step on the
+ * live PB (like select values and pb_hooks).
+ *
+ * NOTE: PB text fields with `max: 0` cap at 5000 chars, NOT unlimited, so
+ * the prompt field gets an explicit max of 50000.
+ *
+ * The two order-assistant switches default to ON (see the design spec:
+ * "Auto-link when sure" is on by default), but a fresh PB bool field
+ * starts every existing row at `false`. So the first run that actually
+ * adds these fields also seeds the ai_settings row with `true`. A later
+ * re-run skips the seeding (the fields already exist), which keeps an
+ * operator's deliberate `false` intact.
+ *
+ * Rollback: delete the fields in the PB admin UI.
