```
tmux.Server.WithProcessEnvironmentValue(name: string) -> (Server, error)
```

WithProcessEnvironmentValue returns a server whose tmux subprocesses receive name=value while preserving the receiver's frozen executable, configuration, and exact socket endpoint. It does not expose an inherited environment snapshot through [Server.ProcessEnvironment]. The result shares daemon-scoped coordination with the receiver. A connection-bound receiver is rejected.
