tmux.Server.SourceFile(ctx: context.Context, request: SourceFileRequest) -> error
```

SourceFile loads or parses one tmux configuration file. The path expands ~ and ~/... for the current user and normalizes redundant separators and dot components without collapsing parent components. Named-user forms are rejected. Exact "-" is rejected because it requires process stdin; a relative path naming a file called "-" remains file data. It can mutate tmux configuration; completed stderr is an error, and cancellation does not prove that parsing or sourcing did not occur.
