Use `WaitForPipeDrain` to deterministically wait for the pipe to drain instead of using `Start-Sleep`. Use `Dispose` instead of `Close` to properly flush and close the pipe stream. Add error handling for connection timeout and I/O errors. Handle `ERROR_BROKEN_PIPE` separately when peeking at pipe, as this happens when the pipe is disconnected immediately after connecting it or after reading the previous message. Don't ignore `ERROR_BAD_PIPE` anymore, as the pipe should never be in a disconnected (i.e. bad) state at this point of the function.
