[BUG] bypassPermissions not working on Windows/WSL — still prompts for Edit/Write

Bug Description

defaultMode: "bypassPermissions" in ~/.claude/settings.json is ignored when running Claude Code on Windows with WSL paths (\wsl.localhost\Ubuntu\...). Claude Code still prompts for permission on every Edit() and Write() call.

Environment

• OS: Windows 11 Pro (10.0.26200) with WSL2 Ubuntu
• Claude Code: latest
• Working directory: \wsl.localhost\Ubuntu\home\dev\Code

Configuration (~/.claude/settings.json)

{
  "permissions": {
    "defaultMode": "bypassPermissions"
  },
  "skipDangerousModePermissionPrompt": true
}

Steps to Reproduce

1. Set defaultMode: "bypassPermissions" in global settings
2. Open Claude Code in a WSL directory
3. Ask Claude to create or edit any file
4. Permission prompt appears despite bypass mode
