Chrome extension connects then immediately disconnects — Chrome disconnected (EOF received) within ~10 seconds every time

What's happening (from logs):
The native host starts successfully and creates a socket, but Chrome sends EOF
almost immediately, causing the host to shut down before Claude Code can
communicate through it. This cycle repeats on every attempt.

Environment:

• OS: macOS Darwin 25.3.0
• Claude Code version: 2.1.76
• Native host version: 0.1.0
• Auth: claude.ai (Pro), email xxxx
• Socket path: /tmp/claude-mcp-browser-bridge-xxxx/

Relevant log file: ~/Library/Logs/Claude/chrome-native-host.log

Pattern in logs:
Chrome native host starting → Socket created → Listening → Chrome disconnected
(EOF) → Stopped
