feat: Marshal and unmarshal @ocap/errors

[sirtimid]

closes#150

Following #149, this PR modifies the marshaling functions in @ocap/streams such that errors from @ocap/errors are unmarshaled into their respective classes, based on the error code. It also extends the stringify utility to support ocap errors.

Nice! I have various questions and suggestions. For all of the errors, I left a number of suggestions on VatNotFoundError that are generally applicable.

Two big changes are harden:ing the error prototypes, error instances, and marshaled errors. You may want to do that after any changes I propose about e.g. reorganizing the types / utils.

Just a couple more things.
