pakrym-oai a70974c1a0 Preserve developer instruction annotations in subagent forks (#40297)
## What changed

- Add a dedicated contextual fragment for developer instructions that emits the
  `generic.developer_instructions` content kind.
- Use the fragment when adding child-specific developer instructions to a
  full-history subagent fork, preserving their classification and ensuring they
  reach the child exactly once without appearing in the parent request.

## Testing

- Extend full-history subagent coverage to verify the child-only instructions'
  annotation, placement, and count.
