Explicitly define move constructor of Streams class. (#107)

Browse Source 
This suppresses the following warning caused by clang-20.

```
error: definition of implicit copy constructor for 'Streams' is deprecated because it has a user-declared copy assignment operator [-Werror,-Wdeprecated-copy]
```

Copy constructor or move constructor is called when std::vector re-allocates
memory. In this case, move constructor should be called, because copying
Streams instances breaks file-descriptor management.

Communication class is modified as well, since it's instance is a member of
Streams class.
