git-worktree-manager 0.1.12

//! End-to-end tests for the hook contracts documented in README.md:
//!
//! - `post_new` fires after `gw new` and a non-zero exit surfaces as a
//!   non-zero CLI exit code (the worktree is left on disk because the
//!   hook runs after `git worktree add`, but the failure is reported).
//! - `pre_rm` fires before `gw rm` removes a worktree, including when
//!   `--force` is passed. `--force` only bypasses the busy-detection
//!   gate, not the user's hook. A non-zero `pre_rm` exit is **advisory**:
//!   gw logs a warning but continues removing the worktree.
//!
//! Unix-only: hooks run via `sh -c` and these tests use `touch` / `exit`.
//! Windows lacks `sh` in $PATH for the test repo, so the same contracts
//! are covered at the unit level in `test_hooks.rs` (which doesn't shell
//! out for the cross-platform cases).
