fix broken pipe issue

[towry]

Problem

When path-git-format is used in a pipeline with commands that close the pipe early (like head -n 1, fzf, or similar), it crashes with a BrokenPipe error instead of exiting gracefully.

Example

zoxide query --list --exclude $PWD | path-git-format --filter --no-bare -f"{path} [{branch}]" | fzf ... | head -n 1
# Error: Os { code: 32, kind: BrokenPipe, message: "Broken pipe" }
