Adam Perry @ OpenAI 3ae0543fdd core: overlap diff root discovery with world state (#30286) ...

## Why

Remote diff-root discovery is independent of world-state construction,
but it ran afterward and added filesystem metadata latency before the
first model request. Overlap the independent work so thread-cold turns
do not pay those waits serially.

## What

- Run `record_context_updates_and_set_reference_context_item` and
`turn_diff_display_roots` with `tokio::join!`.
- Reuse the same resolved display roots when constructing
`TurnDiffTracker`; no cache or behavior lifecycle changes are
introduced.

## Validation

A synthetic executor-skill benchmark with artificial network delay:
thread-cold model-request p50 improved from about 1.79 s to 1.58 s.
