v0.2.1 — User Filtering & Reconfigure Fixes

Bug Fixes

• Stale device on reconfigure — renaming a task or changing a maintenance device no longer leaves the old device behind; the device registry is cleared before reload
• Custom success message — reconfiguring a task/maintenance subentry now shows a proper completion message instead of a generic HA fallback

New Features

• User filtering on task card — new "Filter by user" option in the card editor:
  • My Turn — show only tasks where you are the current assignee
  • In Rotation — show tasks where you are in the assignees list or current assignee
  • Specific person — filter by any person entity
