Support RTL rendering for Arabic text in the chat interface

[ddschairman]

Summary
Arabic text renders with left-to-right alignment in the chat interface, which makes long conversations unreadable. This is a request for automatic RTL support, or a manual toggle.

The problem
Arabic is a right-to-left language. When rendered left-aligned, it becomes difficult to read and error-prone, especially in longer messages.

Specific issues:

Arabic assistant responses are displayed left-aligned.

Tables and headings containing Arabic break or render in the wrong reading order.

Mixing Arabic and English on the same line increases confusion.

There is no manual option to enable RTL rendering.

What I am requesting
Automatic RTL display for Arabic text, based on detected language.

Alternatively, a manual toggle in settings: "Text direction: Auto / LTR / RTL".

Applies to both user messages and assistant responses.

Text direction respected inside tables, lists, and code blocks.

Technical note
Modern browsers support dir="rtl" natively. A minimal implementation:

html

...

The dir="auto" attribute lets the browser detect direction from the first strong character, handling both Arabic and English without a language setting.

Impact
Affects every Arabic-speaking user.

Does not affect English-only users.

Low implementation cost, high user benefit.
