[BUG] Browser extension connection broken in v2.1.25 - works in v2.1.19

Bug Description

The Claude browser extension (claude-in-chrome) fails to connect when using Claude Code version 2.1.25. The same extension works perfectly when downgrading to version 2.1.19.

Steps to Reproduce

1. Install Claude Code v2.1.25 (latest via claude update)
2. Ensure the Claude browser extension is installed and enabled in Chrome
3. Try to use any browser automation tool (e.g., tabs_context_mcp)
4. Receive error: "Browser extension is not connected"

Expected Behavior

The browser extension should connect and respond to MCP tool calls, as it does in version 2.1.19.

Actual Behavior

Error message: "Browser extension is not connected. Please ensure the Claude browser extension is installed and running..."

Workaround

Downgrade to version 2.1.19:

npm install -g @anthropic-ai/claude-code@2.1.19

Environment

• Claude Code version (broken): 2.1.25
• Claude Code version (working): 2.1.19
• OS: Windows 11
• Browser: Chrome (latest)
• Extension: Claude browser extension (installed and enabled)

Priority

This is a critical regression that breaks all browser automation functionality. Please prioritize fixing this issue.

Additional Context

The extension is definitely installed and running - it works immediately after downgrading to 2.1.19 without any other changes. This suggests a breaking change was introduced between 2.1.19 and 2.1.25.
