caixa-resolver 0.1.5

//! Integration test — drive the real resolver against a local bare-git
//! remote. Verifies the full `resolve_lacre` flow: clone → checkout → hash
//! → parse child caixa → transitive walk.
//!
//! No network is used; the remote is an empty temp directory initialized
//! with `git init --bare` and pushed to from a nearby worktree.
