[BUG] RTL/Hebrew text alignment issues in Claude Desktop

What's Wrong?

When writing or reading in Hebrew, text is left-aligned instead of right-aligned. When Hebrew and English appear in the same line, the word order is confusing and unreadable due to missing BiDi (bidirectional text) support. Also, the window close button (X) overlaps the hamburger menu button, making it inaccessible.

What Should Happen?

Text should be right-aligned when Hebrew is detected, and mixed RTL/LTR text should display in correct reading order. The hamburger menu should be accessible without being blocked by the close button.
