Add Profile Counter to Tools

[othmarodev]

Adding Profile Counter to the Tools section, alphabetically near the other visitor counter entries (Visitor Badge, Visitor Count).

What it is

Profile Counter is a self-hosted GitHub profile views counter — a drop-in replacement for komarev.com/ghpvc that you deploy to your own Vercel + Upstash Redis (both free tier).

Why it might fit this list

The Tools section already lists 3 visitor counter services (Visitor Badge, 1990s style, Visitor Count) — all of them third-party hosted. Every few months one of them goes down and users lose their count. profile-counter solves the same problem but self-hosted — the user owns the URL (on their own domain) and the data (their own Redis), and ships with a migration script to preserve their old count from komarev/laobi when those break.

It's ~300 lines of vanilla JavaScript with a Deploy with Vercel button for one-click setup.

Format follows the convention from CONTRIBUTING.md ([Name](link) - Description, capital name, no trailing whitespace).

Thanks for maintaining this list! 🙏
