Just upgraded bifrost to perform single-round batch signing of messages, similar to how bitescrow worked with building covenants.

Batching signatures allows for very fast and robust signing of PSBTs and multi-transaction packages, which will hopefully unlock many kinds of bitcoin protocols over frost and nostr.

The frost2x wallet is almost complete:

```

window.bitcoin = {

getAccount() // done,

getBalance() // done,

getUtxos(amount) // done,

signPsbt(psbt, manifest) // in progress

}

```

Very exciting times ahead!
