//! # oxen clean
//!
//! Remove untracked files and directories from the working tree. Analogous to `git clean -fd`.
//!
//! Without `opts.force` the command is a dry run: it reports what *would* be removed but makes
//! no filesystem changes. Pass `force = true` to actually delete.
//!
//! Invariants:
//!
//! - Never touches `.oxen/`.
//! - Never touches tracked files (candidates come only from `StagedData.untracked_*`).
//! - Never touches files matched by `.oxenignore` (inherited via `oxen status`'s existing
//!   filter; `clean` does not re-filter).
//! - An untracked directory is only removed whole when its entire subtree is untracked —
//!   `oxen status` already classifies partially-tracked directories differently.
