) -> Vec<PruneResult>

Prune a repository, optionally restricted to a specific set of bloat directories.

only is a list of BloatDir::name values. When Some, any bloat directory whose name is not in the list is left untouched and produces no result — this is what makes the interactive selector’s per-directory choices meaningful. When None, every detected bloat directory is pruned.

Same safety invariants as prune_repo.
