/**
 * Single Vercel serverless entry for **single-segment** `/api/:segment` routes (Hobby plan limit).
 * Concrete handlers live in api/_handlers/*.
 *
 * Vercel does not send multi-segment paths (e.g. `/api/auth/session`) to this file — only one
 * dynamic segment after `/api/`. Those URLs need real files such as `api/auth/session.ts` or a
 * `vercel.json` rewrite to a single segment (see `/api/kms/ping` → `/api/wallet-envelope-ping`).
 *
 * `vercel dev` on Windows may spawn extra workers for both this catch-all and explicit `api/auth/*`
 * files; if a worker crashes (exit 3221226505), use `npm run web` or WSL.
 *
 * Includes feed create_topup / mark_read actions (wallet notifications + unread badge).
