Fix not being able to import Wallet interface

[Tristyn]

This exports Wallet interface, NodeWallet class. Previously the Wallet interface was inaccessible

Also gave workspace a type Record<string, Program>

This is a breaking change. Should I fix tests?

Not sure whether this PR is still needed or not?

[Tristyn]

I think so but it's nbd. Anchor exports Wallet which is just a clone of NodeWallet, kinda silly

Feel free to close though if you don't want to clean up and merge this

Recently when doing the VersionedTransaction update I did notice that the Wallet interface doesn't show up in anchor's ts docs. But in general, I don't really understand enough about what's happening in this PR to make a judgement call or clean it up

[Tristyn]

Lets pretend this never happened ;)
