## Summary We are releasing Twenty v2.2.0. This PR sets up the upgrade-version-command machinery for the new release line: - Promote `2.1.0` into `TWENTY_PREVIOUS_VERSIONS` (it just shipped) - Set `TWENTY_CURRENT_VERSION` to `2.2.0` - Reset `TWENTY_NEXT_VERSIONS` to `[]` - Refresh the `InstanceCommandGenerationService` snapshots to reflect the new current version (`2.2.0` / `2-2-` slug) - Update the failing-sequence-runner snapshot to include `2.2.0` in the covered versions list The `2-2/` upgrade-version-command module is already in place and wired into `WorkspaceCommandProviderModule`, so future upgrade commands targeting `2.2.0` can land directly under `2-2/` (or be generated against `--version 2.2.0`).
