SCWID v2.1.0

SCWID 2.1.0 adds editable workout documents and improves shared record
availability across devices.

• Edit Document Beta now keeps Pacers and Lockstep columns, headings and section
  rules aligned with their Print layouts.
• Newly authorized practices, rosters and Seasons are listed as server-only on
  another device until Download is selected; an explicitly downloaded copy remains
  available offline.
• Linux/Crostini startup better selects the secure keyring backend for Remember me
  and the display path for normal shutdown.
• Update installation waits for a clean editor and normal window close. The
  downloaded file is checked again before handoff.

Before upgrading an existing desktop profile: preserve a current database
backup. This version includes forward-only database migration 94; returning to an
older app build after migration requires a compatible pre-upgrade backup and must
not overwrite newer unsent work.

This release uses SCWID's established GitHub update channel as a bootstrap.
Installers and update metadata are unsigned; the independently signed TUF
channel is still being provisioned. Retain the installer from this release for a
supervised repair if needed. macOS and Linux .deb updates require a manual or
system-package installation path.
