tmuxtest.StartPTYProcess(ctx: context.Context, t: testing.TB, binary: string, arguments: []string, environment: []string) -> *PTYProcess
```

StartPTYProcess starts binary with a harness-owned controlling terminal and registers bounded cleanup with t. Its start context owns the child lifetime: canceling ctx terminates the child. Arguments and environment are copied. A nil environment inherits the current process environment; a non-nil empty environment remains empty. binary runs directly without a shell. The PTY backend is supported on Linux only; unsupported platforms call [testing.TB.Fatal]. Setup failures also call [testing.TB.Fatal].
