fix(api): use UInt32Value for ProcessExit status

The status field in ProcessExit was a simple number (uint32). In Proto3, if a number is 0, it doesn't show up in JSON. This was hiding the status code when a process exited successfully.

We changed it to a wrapper type (UInt32Value). Now, even if the status is 0, it will always appear in the JSON output.

Fixes #902
