Module command_executor 

Generic async process runner used by the pg_ctl and initdb wrappers.

The core abstraction is AsyncCommand, a trait with two methods: AsyncCommand::new spawns the OS process and AsyncCommand::execute waits for it to finish (with an optional timeout).

ProcessStatus is a companion trait that maps a process type (initdb, start, stop) to the status values and errors it should produce.

The only concrete implementation is AsyncCommandExecutor.
