🧹 Journal: Entry#summary fits better than Entry#description

- zinc-collective#8
- zinc-collective#10

When I started on this, I started with [changes to the data
layer], because that's where my brain tends to naturally start.

But when I wrote the [system test], I realized it was more of an
[`Entries#summary`].

So I am renaming from `Entries#description` to `Entries#summary`.

Thank you for coming to my TED Talk.

[`Entries#summary`]: zinc-collective#9
[system test]: zinc-collective#9
[changes to the data layer]: zinc-collective#8
