Overview

Adds a composite [state, completed_at] index to chrono_forge_workflows. This supports state-based monitoring (stalled/failed dashboards) and the retention scan ChronoForge::Cleanup runs over completed workflows (the high-volume terminal state), which filters by completed_at. The state prefix also serves the smaller failed-workflow scan.

Shipped as a standalone migration (rather than folded into the install migration) so applications created with an earlier version of ChronoForge can pick it up via ‘rails generate chrono_forge:upgrade`.
