Adds GET /api/topology-runs/{id}/output — trimmed view of the
runs checkpoint (totals + per-turn output previews, capped at
12 turns × 6kB each). The full checkpoint blob can be hundreds
of KB so it was never viable to send through mission polling.
Phase card run rows now expose a "show output" toggle for any
terminal run (completed/failed/cancelled), rendering turns,
tokens, records count, and per-turn agent text. Running rows
still get the live activity stream from the prior slice.
Diagnostic value: on a mission that "completed" without visible
work, this immediately shows whether the agents produced real
output (workspace missing / instructions vague / etc.) or
whether nothing ran at all.
