[🚀 Feature]: Support for HAR export across Chrome, Edge, and Firefox using Selenium Bidi

### Description

I am looking for a way to subscribe to request/response events and parse them into the correct [HAR format](https://w3c.github.io/web-performance/specs/HAR/Overview.html).

Requirements:
- Support for Chrome, Edge, and Firefox.
- Ability to capture full request/response metadata.

### Have you considered any alternatives or workarounds?

I have tried:
- Firefox: Used the `ff-test-bidi-har-export` library.
- Chrome/Edge: Attempted using the Chrome DevTools Protocol (CDP).
