Background tasks don't sync changes to working directory when completed

Description

When running tasks in the background via Claude Code CLI, if the task makes changes, commits them to a feature branch, and pushes to remote, the local working directory doesn't automatically receive those changes when the task completes or when resuming.

Current Behavior

1. User starts a background task
2. Task makes file changes
3. Task commits to a feature branch and pushes to remote
4. Task completes
5. User resumes/checks results but local working directory doesn't have the new files
6. User must manually pull/merge to get the changes

Expected Behavior

When a background task completes, the changes should be available in the local working directory without requiring manual git operations. Options could include:

• Automatically merge the feature branch back to the working branch
• Keep changes staged/committed on the current branch instead of a separate feature branch
• Provide a prompt to sync changes when task completes
• Auto-pull when resuming a completed background task

Impact

This creates a confusing workflow where:

• The task reports success
• Files appear to be created (in the task output)
• But the user can't see or use the files until manual git operations
