git-cross

Use when changing `git-cross` behavior in `Justfile.cross`, `src-go/main.go`, `src-rust/src/main.rs`, or related tests. Focus on parity, path safety, and minimal correct changes.

Use when a `git-cross` behavior change needs test planning or verification, especially for sync, diff, status, patch, push, path resolution, and cross-implementation parity.

Use when reviewing risky `git-cross` changes involving `patch`, `sync`, `push`, `remove`, `prune`, root paths, `rsync --delete`, metadata, or `.crossignore` semantics.

Use when writing or revising feature specs for `git-cross`, especially for new commands, new modes, UX changes, root patching, or `.crossignore` behavior.
