## Why
Changes to the selected working directory can select different `AGENTS.md`
instructions. These updates need to reach the model even when the deferred
executor feature is disabled.
## What changed
- Refresh environment readiness and `AGENTS.md` before capturing each step.
- Record model-visible world-state changes for every session instead of gating
them on the deferred executor feature.
- Preserve the initial environment context without duplicating it.
## Testing
- Cover `AGENTS.md` replacement after a working-directory change.
- Verify that initial environment context remains unique with the deferred
executor both enabled and disabled.
