Agent instructions

The conventions for this repository live in skills.md. Read it before writing or reviewing code here, and follow it over generic Express advice.

Short version:

• Express 5 + Mongoose 9 + TypeScript (ESM, NodeNext), run by tsx locally and deployed to Vercel's zero-config Express runtime. The default export in src/app.ts is the deployment; server.ts keeps app.listen for local and Docker.
• The layout is src/modules/<domain>/ with routes → controller → service → serializer. Named exports only, .js extensions on relative imports, no asyncHandler (Express 5 forwards rejected promises).
• Zod lives in src/shared and is independent from the client repo's copy. Update both sides by hand after a contract change.
• No Redis. Auth stays Bearer JWT until a task explicitly asks for the httpOnly cookie migration.
• Project images and the resume PDF live in Cloudinary; nothing is read from or written to the filesystem, and no image bytes go into MongoDB.
• Chat in Bangla + English; code and comments stay English.
