alef 0.77.0

//! Regression coverage for alef #148: `sync_versions` bumped every `Cargo.toml` it owned
//! without ever refreshing the sibling `Cargo.lock`, so `alef validate versions` — which
//! discovers lockfiles through a separately-derived, broader enumeration — found the stale pin
//! and failed the release gate. Three releases were tagged and pushed with a stale lockfile,
//! failed validation, and never reached crates.io.
//!
//! The fix makes the write side and the read side call the exact same discovery
//! (`crate::cli::commands::version_manifests::discover_cargo_locks`). The test below is the
//! actual deliverable: it does not merely check that a lockfile got new bytes, it runs
//! `sync_versions` and then `validate versions` back to back and asserts the gate passes —
//! proving the write set and the validate set agree, not just that each individually "works".
