Glob import client islands by default

[bensmithett]

tropical-islands requires you to manually import and list your hydratable island components in your client bundle. It's not difficult, but it does feel very manual.

In Tropical's entry-client.jsx we could glob import something like components/**/*.client.jsx and build that list automatically...

Pros

• .client.jsx matches React server components' convention
• Simple naming convention is probably easier to learn and remember than adding a component name to a list

Cons

• More magic, kind of goes against what I'm aiming for with Tropical in keeping it just a bunch of simple, readable, hackable files and not a framework that bundles up a bunch of magic

Alternatively I could just leave that approach in entry-client.jsx as a commented out example 🤔
