jif 0f7c8608bd Capture Guardian review checkpoints from live context (#46512) ...

## Why

Committing a Guardian review snapshot currently flushes and reloads the transcript from storage, even though the completed model context is already available in memory.

## What changed

- Build forkable checkpoints directly from live session state, preserving model history, retained Guardian context, world state, turn context, and token usage.
- Preserve compaction window metadata and MCP resource origins in the checkpoint.
- Recognize prior user turns inside compacted replacement history.

## Testing

Add round-trip checkpoint tests for legacy and thread-owned Guardian context without storage, including preservation after live history is mutated. Extend the review compaction test to assert that checkpoints do not load history from storage.
