/**
 * GET /api/me/following
 *
 * Returns the IDs of all users the authenticated user follows.
 * Used client-side to filter the Supabase Realtime Presence channel —
 * Realtime has no native server-side filter, so the frontend needs the list.
 *
 * No pagination — follows rarely exceed 1 k for a single user.
 *
 * Response:
 *   { userIds: string[] }
