Add RTL (Right-to-Left) support in VSCode extension for Arabic language

Feature Request

Description

The VSCode extension currently lacks RTL (Right-to-Left) text support, which makes it difficult to use with Arabic language input and output.

Problem

When using Claude Code's VSCode extension with Arabic text:

• Text alignment is incorrect (displayed LTR instead of RTL)
• Arabic characters and sentences are not rendered in the proper reading direction
• Mixed Arabic/English content is hard to read and navigate

Requested Feature

Add proper RTL support in the VSCode extension, including:

• Automatic detection of RTL languages (Arabic, Hebrew, Persian, Urdu, etc.)
• Correct text alignment and direction for RTL content
• Proper handling of bidirectional (mixed LTR/RTL) text
• RTL support in both input and output areas of the extension

Use Case

Users who communicate in Arabic (and other RTL languages) need proper text rendering to effectively use the extension. This is important for accessibility and internationalization.

Additional Context

Arabic is one of the most widely spoken languages globally, and proper RTL support would make the extension accessible to a large user base.
