oxiarc-cli 0.3.0

//! Integration test for `oxiarc list --tree` hierarchical rendering.
//!
//! Creates a ZIP fixture with nested `dir1/a.txt`, `dir1/b.txt`,
//! `dir2/sub/c.txt`, `dir2/sub/d.txt`, and a top-level `root.txt`, then
//! runs `oxiarc list --tree` against it and verifies that tree connectors
//! (`├`/`└`) appear and all five filenames are present in stdout.
//!
//! This locks in the verify-and-close behaviour for the CLI tree view:
//! `print_tree` in `src/utils.rs` is the single source of truth, and this
//! test guards against regressions in its hierarchical rendering.
