auto-claude: subtask-1-1 - Add filter after map operation to remove empty str (#1466)

Fix incorrect uncommitted file count display after refreshing a task.
The issue was that empty strings from .substring(3).trim() operations on
short/malformed git status lines were not filtered out, inflating the count.

This adds a second filter after the map to remove empty strings:
.filter(file => file)
