upskill 0.6.3

//! ATDD tests for `pipeline::install_with_lockfile`.
//!
//! Validates that a successful install writes a `schema: 1` lockfile
//! (`.upskill-lock.json`) at the consumer-project root with one entry
//! per `(kind, name)` carrying the source label, optional git ref, and
//! SSOT content hash.
