What's Wrong?

Title:
--chrome flag: "No Chrome extension connected" despite Chrome, extension, and native host all running

Body:
## Environment

  • Claude Code CLI on Windows 11 Pro (10.0.26200)
  • Chrome running with Claude extension active
  • chrome-native-host.exe confirmed running via tasklist
  • Started with: claude --dangerously-skip-permissions --chrome "run precrime"

## Bug
Every mcp__claude-in-chrome__tabs_context_mcp call returns "No Chrome extension connected" despite:

  1. Chrome is open with tabs active
  2. The Claude Chrome extension is installed and showing as connected in the browser
  3. chrome-native-host.exe process is running
  4. The --chrome flag was passed at launch

Tried 15+ calls across tabs_context_mcp, tabs_create_mcp with various parameters. Same error every time. No recovery path available from
within the session.

This has recurred across multiple sessions over multiple days on Windows 11.

## Expected
Chrome tools should connect when --chrome is passed and the extension is active.

## Steps to Reproduce

  1. Install Claude Chrome extension
  2. Open Chrome, verify extension is active
  3. Launch Claude Code CLI with --chrome flag
  4. Call any mcp__claude-in-chrome__ tool
  5. Get "No Chrome extension connected" error every time

What Should Happen?

Claude should connect to the open chrome window and not argue with me
