felixxia-oai 5d3f8752fc Preserve prewarmed reasoning effort across replay and early rollback (#44285) ...

## Why

Initial history replay and rollback before the first turn could clear the reasoning-effort baseline established by startup prewarm, preventing the first request from preserving that baseline when the selected effort changes.

## What changed

Preserve the reasoning-effort pin during history reconstruction. Clear it on rollback only after startup prewarm has been consumed. With reasoning-effort overrides enabled, a prewarmed `medium` baseline remains on the request while a subsequent `high` selection is sent as a `configuration_update`.

## Testing

Add regression coverage for prewarm completing before initial replay on resume and fork. Expand WebSocket tests to cover resumed and forked threads with overrides enabled and disabled, plus rollback before the first turn.
