Problem

When authenticating Claude CLI via dr-claw, the CLI runs inside a server-side PTY where browser launch fails silently. The CLI shows a "Paste code here" prompt but the OAuth URL is not reliably detected or forwarded to the user's browser.

Partially fixed: 0a85acd resolved Windows CLI detection, but the browser/OAuth flow issue remains.

Expected

The auth URL should be automatically detected and opened in the user's browser via the frontend.

Suggested Fix

1. Frontend (src/components/Shell.jsx): When receiving auth_url with autoOpen=true, auto-call openAuthUrlInBrowser()
2. Server (server/index.js): Add Claude CLI-specific URL detection patterns (e.g., paste code here, visit this url) to shouldAutoOpenUrlFromOutput
3. Server: Set BROWSER=none in embedded shell env to force CLI to print URL as text instead of attempting browser launch
