Fix: scannable QR login for terminal agents
wa_get_login_qr previously returned an ANSI-colored terminal QR that renders fine in Claude Desktop but shreds into literal escape codes when piped through a terminal agent (e.g. Claude Code), making it unscannable.
The default format is now auto, which returns three representations so at least one always works in any client:
- A real black-on-white PNG saved to
WA_DATA_DIR/login-qr.png— scannable anywhere (openit). - An inline MCP image block — renders in Claude Desktop / image-capable clients.
- An ANSI-free ascii preview rendered straight from the QR matrix (tuned for a dark terminal).
Also adds an explicit png format; ascii/dataurl/raw unchanged.
