MuSig2 between Core, ColdCard and Ledger (vibe code trigger warning)

Once setup, using it is easier, especially between two core wallets.

However Ledger isn't going to sign anything without first registering the BIP388 policy, and then passing it back (along with an hmac) at signing time.

Core can't currently produce this BIP388 policy and it can't store the hmac provided by the ledger. So you'd have to use the Ledger drivers manually (lookup Moosig). Not fun.

I forgot what ColdCard requires, if anything, maybe passing psbt's around already works?

MuSig2 is already in Core! Just no hardware wallet support and very tedious to setup even between two core wallets.

It's unrelated, though it might be useful to include Nunchuck in an interop test.

They might need similar changes on the Bitcoin Core side? I haven't studied their implementation yet.

Slow progress, but this PR gives a sketch of what's possible. Don't use this on mainnet, or at all :-)

I like to keep such experiments on my own fork, and then incrementally PR things to the main repo. But this isn't my main focus at the moment, so don't hold your breath.
