[Bug] Chrome browser validation failing: MCP integration broken, auto-launch disabled, Playwright MCP not functioning

Bug Description
The use of Chrome for validation is not working well. Before, I could use it without problems, but now it doesn't manage to do the minimum requested work. Before, it would open Chrome if it wasn't open, now it just complains - I have to open it myself, and if there's another window it gets confused. Before, Claude appeared in the tab group, now it shows Claude (MCP). Before, I could ask it to use Playwright's MCP instead of Claude, now it doesn't handle it well. To verify, since I've performed this operation several times before, I've tested with Ampcode and Playwright's MCP and it works without problems.
