Nothing consumed GitWorktreeInfo.locked: a locked worktree is a real checkout and stays a usable workspace, so no caller needs to distinguish it. Unknown porcelain keys are already ignored, so parsing it was speculative. The parser test still feeds a real `locked` line and asserts it is ignored, and the service test still pins that a present, non-prunable worktree is kept, so the policy stays covered without the field.
