fix(brief): bundle resvg linux-x64-gnu native binding with carousel fn

Real root cause of every Telegram carousel WEBPAGE_CURL_FAILED since PR #3174 merged. Not middleware (last PR fixed that theoretical path but not the observed failure). The Vercel function itself crashes HTTP 500 FUNCTION_INVOCATION_FAILED on every request including OPTIONS - the isolate can't initialise. The handler imports brief-carousel-render which lazy-imports @resvg/resvg-js. That package's js-binding.js does runtime require(@resvg/resvg-js-<platform>-<arch>-<libc>). On Vercel Lambda (Amazon Linux 2 glibc) that resolves to @resvg/resvg-js-linux-x64-gnu. Vercel nft tracing does NOT follow this conditional require so the optional peer package isnt bundled. Cold start throws MODULE_NOT_FOUND, isolate crashes, Vercel returns FUNCTION_INVOCATION_FAILED, Telegram reports WEBPAGE_CURL_FAILED. Fix: vercel.json functions.includeFiles forces linux-x64-gnu binding into the carousel functions bundle. Only this route needs it; every other api route is unaffected. Verified: - deploy-config tests 21/21 pass - JSON valid - Reproduced 500 via curl on all methods and UAs - resvg-js/js-binding.js confirms linux-x64-gnu is the runtime binary on Amazon Linux 2 glibc Post-merge: curl with TelegramBot UA should return 200 image/png instead of 500; next cron tick should clear the Railway [digest] Telegram carousel 400 line.
