"""Lock down the RTL bidi auto-detection contract on the chat composers.
The browser's Unicode bidi algorithm only flows Arabic / Hebrew / Persian /
Urdu right-to-left when the textarea carries `dir="auto"`. The three
composer surfaces (main chat, inline edit, compare mode) each need the
attribute, and the IME / i18n Playwright smoke must keep its env contract
minimal (no dead `STUDIO_OLD_PW`).
