```ts
type TmuxInvocationRequest = {
  readonly commands: readonly [TmuxCommand, ...TmuxCommand[]];
  readonly daemonGuard?: DaemonGuard;
  readonly environment?: Readonly<Record<string, string | undefined>>;
  readonly executable: string;

What an engine is asked to run: one ordered command list, and the daemon it must still be talking to.

tmux runs a command list until one fails and discards the rest, so the list
is the unit of atomicity a caller gets. The daemon guard is what stops a
raw tmux id being applied to whatever a restarted server reissued it to.
