Summary

This PR replaces the external tauri-driver setup with an embedded BitFun WebDriver server and then follows up with protocol coverage and compatibility fixes.

Included Changes

• add a new bitfun-webdriver crate with an embedded WebDriver HTTP server, protocol router, bridge execution layer, platform screenshot/print support, and session state management
• wire the embedded WebDriver into the desktop app startup path and add bridge result handling plus webdriver-specific logging behavior
• switch the E2E config from tauri-driver to the embedded driver launcher and update the E2E docs/readme accordingly
• expand protocol coverage for navigation, window, frame, element, shadow root, actions, alert, cookie, log, screenshot, print, and script endpoints
• add protocol-focused WDIO coverage plus the local repro skill for embedded webdriver debugging
• fix follow-up compatibility issues around XPath lookup, modifier propagation for pointer/wheel events, implicit wait handling, page load waiting, and stale frame/action state after navigation or window switches
