gsxdsm 5f70447a62 FN-8108: require resolution for triage duplicate tasks

Require explicit resolution for triage-detected duplicate tasks.

- Add configurable prompt, keep, and delete handling for explicit duplicate markers.
- Surface linked duplicate decisions in task details and scheduling settings.
- Preserve task failure provenance and strengthen lifecycle recovery coverage.
