Add ai-browser-bridge to Tools & Utilities

[legisus]

Adds ai-browser-bridge — a local bridge (MV3 extension + 127.0.0.1 WebSocket relay + CLI) that lets Claude Code or any terminal AI agent drive the user's real, logged-in Chrome through chrome.debugger: trusted input events (isTrusted: true), CSP-proof Runtime.evaluate, authenticated downloads, print-to-PDF, and screenshots — all in background tabs without stealing focus.

Security model: localhost-only binding, mandatory token auth, optional per-domain allowlist, full command audit log. MIT licensed, three source files, one dependency.

Entry follows the existing format and is placed at the star-sorted tail of Tools & Utilities.

Small real-world demo since submitting this: I used ai-bridge to have a terminal agent drive Gemini in my own logged-in Chrome (background tab, trusted input) and generate the illustration for this week's AI-news post on my LinkedIn: https://www.linkedin.com/feed/update/urn:li:activity:7482555780693405696/

That's the eval + background-tab flow from the README doing actual weekly work, not a toy example.
