Adds Passwordless Login with Email OTP and Magic Link in Express (Mailtrap) under JavaScript > Node.

• Author disclosure: I'm the author of this repository.
• Free and open: MIT-licensed, public, no paywall or signup.
• What the reader builds: a complete working passwordless login for Express (6-digit email codes and magic links, hashed single-use codes, attempt limits, rate limiting, server-side sessions, emails through the Mailtrap API) with TypeScript and SQLite. The README walks through the setup, the flow, the security design and the key code, and the repo has a test suite to build against.
• Honest scope note: it is a documented project with a README walkthrough rather than a multi-part written tutorial. If that is out of scope for this list, I'm happy to withdraw the pull request.

Checks: python3 scripts/check_readme.py lint exits 0 (errors=0, warnings=0), and the entry uses the - [Title](link) format with a direct link.
