A job can reach `shipped` via autoship PATCH, the `ship` operator action, or a
terminal lease release, but the run-level `result` was left at whatever the
factory last reported (e.g. `review`), so the dashboard showed a shipped job with
a non-terminal run result.
- Add markLatestRunShipped(): on any transition to `shipped`, set the latest run
result to `shipped` (+ endedAt if unset). Idempotent, best-effort.
- Wire it into patchJobFenced (ungated; budget accrual stays flag-gated) and the
`ship` operator action.
- Document the testing->shipped paths (factory autoship vs `ship` operator action)
and the run-mirroring in docs/GIGAFACTORY/FLEET_CONTROL_PLANE.md.
Tests: +2 (patchJobFenced->shipped and operator ship both set run.result=shipped).
Fleet suite 180 pass; tsc clean.
