WebDriver BiDi Milestone 19 - In Development

Goal: This milestone will focus on delivering high-priority APIs required for experimental WebDriver BiDi support in Playwright, including capabilities such as CSP bypass, correctly applying user context configurations when invoking `window.open`. In parallel, we will enable widget-level touch event support for web-platform tests and continue evolving the BiDi framework to properly support chrome browsing contexts and workers. This work is foundational for future use cases, including controlling Firefox via MCP servers.
