feat: integrate II-Agent with browser extension (ii-browser)

[namtranii]

ii-browser

⚠️ Beta — under active development. This build can handle basic browsing, tab orchestration, and read/write tasks. The Domain Modules (YouTube, Google Docs, Google Sheets, Google Slides) are still being tested and iterated on — expect rough edges.

About

ii-browser is a Chrome/Edge/Firefox extension that puts the ii-agent assistant into a sidepanel, so II-Agent can read, navigate, and act on the page you're on. It ships many tools covering tab and window control, accessibility-snapshot-driven clicks/typing, screenshots, bookmark and history management, and product-specific modules for YouTube, Google Docs, Sheets, Slides and more.

Built on WXT + React 19 + Tailwind v4 (MV3).
