chore: release 0.2.1 (#30)

- Cargo.toml, npm/decibri-cli/package.json: 0.2.0 -> 0.2.1 so the
  crate and npm packages publish together through trusted publishing
  (0.2.0 published to crates.io only). No functional change.
- Cargo.lock: refresh decibri-cli to 0.2.1
- CHANGELOG.md: 0.2.1 entry
- tests/snapshots: version snapshot value updated to 0.2.1 (field
  set unchanged; schema still locked)
