docs: repoint stale workflow_orchestrator.md refs to commands/delegate.md

The orphan system-prompts/workflow_orchestrator.md was deleted in the
previous commit. Update the four secondary docs that still referenced
it. CHANGELOG entry left untouched (historical record).

- ARCHITECTURE_QUICK_REFERENCE.md: troubleshooting checklist + multi-step
  workflow example now point at inject_all.py and the slash command.
- environment-variables.md: Related links collapsed to commands/delegate.md.
- plan-explore-parallel-processing.md: 4 architectural references updated.
- validation-schema.md: Related Documentation pointer updated.
