## Why
A remote process can finish while a network policy review is still pending. Normal process cleanup should withdraw that review without turning the completed command into a review failure or losing its output.
## What changed
- Record whether a network policy request was withdrawn because the process finished, was cancelled, lost its executor connection, or timed out.
- Treat normal process completion as cleanup while retaining fail-closed behavior for other cancellation causes.
- Preserve explicit network denials before policy persistence so cleanup cannot replace the reported call outcome.
## Testing
Add an integration test that completes a remote process during a pending network review and verifies that the command reports its successful exit and output without approving the withdrawn request.
