sayan-oai 0a6616f4cf Mark the primary environment in model context (#35874) ...

## Why

When a turn uses multiple environments, the environment context lists each one but did not identify which environment is primary.

## What changed

- Add a `primary` attribute to each environment in multi-environment model context.
- Persist primary selection in world-state snapshots and emit updates when the primary environment changes.
- Restate environments when transitioning between single- and multi-environment context, while preserving the existing single-environment format.

## Testing

- Cover primary-environment changes, single/multi-environment transitions, legacy snapshot compatibility, and deferred-executor promotion after environment startup.
