Note

Medium Risk
The release bundles install trust-policy behavior (#1418) and Linux store/CAS publishing (#1419), which affect supply-chain checks and artifact layout even though this PR is mostly version bumps.

Overview
Release PR that cuts v2.2.4 across the workspace: [workspace.package].version and every aube-* entry in Cargo.lock move 2.2.3 → 2.2.4, and release.json records the new version and release timestamp.

Per-crate CHANGELOG sections document what ships in this tag: #1418 fixes install so lockfile-resolved packages are trusted without revalidation (main aube / aube-settings); #1419 changes Linux CAS publishing to use file descriptors (aube-store); #1417 refreshes benchmark results (noted on all crates). No application Rust changes appear in this diff—only release metadata and notes.
