Subject: [PATCH 21/87] reordered smart pointer exercises

Switched rc and arc so rc comes first, since arc is, like the name implies, atomic rc. This gives the exercises a more logical progression.
Moved all smart pointer exercises (box, rc, arc, cow) under threads into their own section. Threads are used in the smart pointer exercises, so they should be introduced first.

Subject: [PATCH 59/87] chore: fix prompt error

Missed a blank line, which causes the prompt incorrect like below:

```rust
You can keep working on this exercise,
or jump into the next one by removing the `I AM NOT DONE` comment:

 6 |  // Make this code compile by using the proper Rc primitives to express that the sun has multiple owners.
 7 |
 8 |  // I AM NOT DONE
 9 |  use std::rc::Rc;
```

Subject: [PATCH 78/87] refactor(cow1):  replace main with tests

Following the discussion in #1195 this is the best I could come up with.
The issue for me (and apparently a few other learners) was that the code
needed to complete the exercise was not _missing_, but was rather there
but wrong.

In the end, what made the difference between this exercise and others
(for me) was that in this exercise I was supposed to learn what to
*expect* of an output. So I think it makes sense here to let the learner
modify the tests and not the code itself.

Fixes #1195
