v1.0.20: fix button icons and surface user-fetch errors

- Remove stale idle.svg/running.svg from zip (were shadowing the PNG
  icons added in v1.0.15, causing old grey icons to show instead of
  the Aurora timer images)
- Fix package script to always delete and recreate zip so removed files
  don't persist across builds
- Show a clear error in the name dropdown when fetchUsers fails (e.g.
  Notion integration missing "Read user information" capability)
