Defer Guardian context limits to request preparation (#61185)

Browse Source 
## What changed

Preserve original root conversation evidence, retained instructions, assistant context, and verified answers until request preparation. Apply shared section preparation to both synchronous and asynchronous reviews, preserving fixed limits and omission notices while allowing elastic preparation to use the originals. Cache the fixed root view for reuse.

Split classifier setup from final input assembly and normalize new images before deduplication and token accounting, preserving committed history.

## Testing

Extend tests for fixed and elastic preparation across both review profiles, original root evidence after handoff, and image normalization during retained-request preparation.
