v2026.6.21

Fixed

• Fixed the update notice to include a changelog URL when one is available.
• Fixed pi update to install the exact version returned by the Pi update check, make --force reinstall that checked version, fail instead of falling back to an unversioned reinstall when no version is available, and report both the old and updated versions.
• Fixed senpi --list-models to show the full model catalog instead of only models available under the current credentials.
