Summary: Claude Code adds auto-backgrounding for bash

Why It Matters: This change makes the tool work better for long tasks. It means users can keep working without waiting.

What Changed:

• A new version, v2.0.19, was added.
• Claude Code will now automatically run long bash commands in the background.
• Users can change how long bash commands run before being backgrounded using BASH_DEFAULT_TIMEOUT_MS.
• A bug was fixed where Haiku was used too much in print mode.
