felixxia-oai 16ff14c266 Retain inherited Guardian instructions in standalone forks (#43478) ...

## Why

A standalone root forked from a worker needs its inherited user instructions for Guardian review, including after compaction. Parent input counters belong to a different thread, and omitted parent answers may have restricted an inherited authorization.

## What changed

- Adopt inherited user instructions into thread-owned retained context for standalone roots, recovering surviving checkpoint messages when needed.
- Keep inherited instructions before local evidence without sharing local acceptance counters, and preserve that distinction during reconciliation and rollback.
- Mark parent verified answers as incomplete and treat recovered checkpoint instructions as incomplete excerpts.

## Testing

Add coverage for standalone forks from copied history and truncated checkpoints, retention through compaction and resume, inherited/local ordering collisions, and rollback scope.
