chore(release): 0.22.1 - #97

The diff bumps the workspace version from 0.22.0 to 0.22.1 without changing any code or dependency pins, and without adding, removing, or altering any comment in the repository. The change to `Cargo.toml` is a single version-integer increment in `[workspace.package]`. This is a routine patch release bump; nothing in the diff itself introduces a defect, regression, or rule violation. The `Cargo.lock`, release workflow, and CI contract expect such bumps to be committed through a reviewed PR, which is what this is. No lookups are needed.

No findings.
