[BUG] Chrome extension side panel works but CLI bridge doesn't connect

The Claude Chrome extension side panel functions correctly (can browse, click, scroll, take screenshots) but Claude
Code CLI cannot establish connection via MCP bridge.

Environment:

• OS: Windows 11
• Claude Code: v2.1.30
• Extension ID: fcoeoabgfenejglbffodgkkbkcdhcgfn
• Account: Pro subscription, logged into same account on both

Steps to Reproduce:

1. Install Claude Chrome extension
2. Verify side panel works (it does - can interact with pages)
3. Run claude CLI
4. Run /chrome command
5. Try any mcp__claude-in-chrome__* tool

Expected: CLI connects to browser
Actual: "Browser extension is not connected" error

What Works:

• Extension side panel ✅
• Page debugging banner shows ✅
• Side panel can click/scroll/screenshot ✅

What Doesn't Work:

• CLI → Chrome MCP bridge ❌

Troubleshooting Tried:

• Full Chrome restart
• Full CLI restart
• Reinstalled extension
• Reset ~/.claude.json
• Ran /chrome multiple times
