[Bug] Bun runtime assertion failure in --chrome-native-host on Windows 11

Bug Description
---
Bug: claude.exe --chrome-native-host crashes on Windows with Bun runtime assertion failure

Environment:

• OS: Windows 11
• Claude Code: v2.1.37 (latest) — also reproduced on v2.1.25 (stable)
• Bun: v1.3.9-canary.51 (latest) / v1.3.5 (stable)
• Chrome Extension: Claude v1.0.47 (ID: fcoeoabgfenejglbffodgkkbkcdhcgfn)

Impact:
Chrome extension cannot connect to Claude Code. All mcp__claude-in-chrome__* tools return
"Browser extension is not connected."

Root Cause:
claude.exe --chrome-native-host crashes immediately on startup with Bun panic(main
thread): Internal assertion failure. This prevents the native messaging host from bridging
Chrome extension to Claude Code.

Crash Output:
[Claude Chrome Native Host] Initializing...
[Claude Chrome Native Host] Creating socket listener:
\\.\pipe\claude-mcp-browser-bridge-0646
panic(main thread): Internal assertion failure
oh no: Bun has crashed.

Reproduce:
Run claude.exe --chrome-native-host from any terminal on Windows.

Verified working:

• Native messaging host registered in registry

(HKCU\Software\Google\Chrome\NativeMessagingHosts)

• Named pipe \\.\pipe\claude-mcp-browser-bridge-0646 is accessible
• Chrome extension installed with nativeMessaging permission
• chrome-native-host.bat points to correct claude.exe path
