v0.0.28

Tested against DBOS 2.23.0 — see tested_dbos_version in GET /version and dbos-argus --version. Argus tracks the latest DBOS schema and does not aim for backward compatibility; the dependency floor is now dbos>=2.23.0. Pointing Argus at an older DBOS database whose dbos.workflow_status lacks completed_at will error on the workflow list / detail reads.

Added

• Workflow completion time. DBOS 2.23.0 added dbos.workflow_status.completed_at,
  the canonical wall-clock timestamp for when a workflow reached a terminal
  state. Argus now reads it: it appears as completed_at on the workflow
  list and detail API/realtime payloads, and the workflow detail pane shows
  a Completed row and computes the workflow Duration from
  started_at → completed_at (falling back to updated_at while still
  running). Null for workflows that haven't finished.

Changed

• Schema snapshot regenerated against DBOS 2.23.0 (closes the dbos-watch
  drift issue). workflow_status.completed_at is now argus-tracked.
• Bumped the dbos dependency floor to >=2.23.0 to align Argus with the
  DBOS release that introduced completed_at.
