mcp.caller.CallerIdentity.from_values(tmux: Option<OsString>, pane: Option<OsString>) -> Option<Self>
```

Build an identity from explicit values, as the environment would give them.

Separate from [`CallerIdentity::from_env`] so the parsing can be tested
without a process-wide environment, which no test can hold alone.
