Feature request: auto-enable --ax-screen-reader for screen reader users

claude ships a great flag, --ax-screen-reader, that renders flat text with no decorative borders or animations - ideal for screen reader users (JAWS/NVDA). Problem: it is opt-in and undiscoverable unless you already know to check claude --help. A blind/low-vision user hitting the default interactive UI gets constant repainting and decorative symbols (e.g. spinner triangles) with no obvious way to know a fix exists.

Ask: detect an active screen reader at startup (Windows: SPI_GETSCREENREADER; similar APIs exist on macOS/Linux) and auto-apply --ax-screen-reader, or at minimum surface it during claude doctor/first-run setup so users do not have to stumble onto it via --help.

(Filed on behalf of a JAWS screen reader user. The in-app /feedback//bug commands were disabled by org policy on this account, so filing here instead.)
