- SelfPodInfo gains inheritedEnvValueFrom (V1EnvVar[]) and inheritedEnvFrom (V1EnvFromSource[])
- Container selection now prefers the container named "paperclip", falls back to first
- buildJobManifest appends valueFrom env vars (skipping names already overridden)
and sets envFrom on the opencode container when present
- Tests updated: mock updated, 5 new cases covering secretKeyRef forwarding,
dedup, envFrom passthrough, and empty-envFrom omission
