/**
 * Migration: add `coordinates` (geoPoint) to the `companies` collection.
 *
 * Why this exists
 * ───────────────
 * Companies need a location for future routing / delivery work (we'll
 * either query nearest-company for order allocation, or build a small
 * internal delivery app so the driver team can see where they're going).
 * Today the field is unstored; tomorrow it's the foundation of those
 * features.
 *
 * Schema
 * ──────
 *   companies.coordinates    geoPoint (optional in form)
 *
 * Why `geoPoint` and not `text "lat, lng"`
 * ────────────────────────────────────────
 * Decision (operator): use the native PB `geoPoint` type. Customers +
 * suppliers store coordinates as combined text (`"-26.123, 28.456"`)
 * with a `parseCoordinates` helper on the supplier map. Companies
 * diverge on purpose so we can use PB's `within` filter for radius
 * queries without re-parsing. If the project later wants a single
 * convention across all three collections, that's a separate migration.
 *
 * PB geoPoint gotcha
 * ──────────────────
 * The field is non-nullable with a zero default of `{"lon":0,"lat":0}`
 * ("Null Island" in the Atlantic). UI must treat `{0, 0}` as empty,
 * otherwise every company shows up at sea. Form submits also send
 * `{0, 0}` for blank — the UI is what hides it.
 *
 * Idempotent — safe to re-run.
 *
 * Run with:
 *   npx tsx scripts/migrations/2026-06-28-add-companies-coordinates.ts
