/**
 * Column definition helpers for defineTable.
 *
 * These produce config objects that defineTable maps to Drizzle column builders.
 * Plugin developers use these instead of importing from drizzle-orm/pg-core directly.
 *
 *   import { defineTable, column } from "@porulle/db";
 *
 *   export const giftCards = defineTable("gift_cards", {
 *     // Per-org unique (default): UNIQUE (organization_id, code)
 *     code: column.text({ unique: true }),
 *     // Globally unique across all tenants: UNIQUE (public_code)
 *     publicCode: column.text({ unique: "global" }),
 *     balance: column.integer(),
 *     status: column.text({ enum: ["active", "disabled"], default: "active" }),
 *   });
 *
 * Child tables (FK to org-scoped parent) have no organizationId; unique: true
 * creates UNIQUE (col) on the child column.
