Terminal display gains groundwork for right-to-left text

What

Claude Code draws its interface in the terminal with its own renderer. It gains support for text direction, meaning left-to-right or right-to-left writing:

• The ink-text Text component accepts a dir property and passes it on as the textDirection style.
• The renderer adds a writeDirected path that puts a left-to-right or right-to-left mark in front of text and right-aligns right-to-left text within the available width.
• Two helpers, keepColumns and trailingSpaces, support this.

All of it sits behind a check, so it does not necessarily apply everywhere yet.

Why

Right-to-left languages such as Hebrew and Arabic can be laid out the right way round in the terminal where this is in use.
