We'll just re-use the funding key instead. Alternatively, we could use the _other_ party's key here.
Doesn't add anything atm, so might as well drop it.
This also adds the new partial signature encoding which uses the final nonce which is needed for final signature combination.
In this commit, we build off the prior JIT nonce proposal modifying the
following:
* The funding flow returns to being symmetric. Both `open_channel` and
`accept_channel` carry nonces.
* The `shutdown` message once again transmit a nonce that'll be used
by both sides to sign the shutdown transaction. A symmetric nonce
approach is used here as both sides already know what the other will
use for their nonce, and there's only a single message to sign.
* The `closing_signed` message now only carries a 32-byte
`partial_sig` value, as the nonces has already been transmitted
ahead of time. Additionally, the existing "negotiation" feature has
been done away with. Cooperative close will now always succeed after
a single round, as the initiator is the only that ultimately pays
fees.
bolt-simple-taproot: make funding symmetric, add new type for shutdown
A NUMs point means we can do normal recovery scans for a remote output like we do today.
In this commit, we modify the to_loccal revocation path to use the existing NUMs point to force all sweeps via a tapscript reveal. This ensures that the internal key is always revealed so the anchor output can always be swept.
Clarify + simplicity over cleverness

…reated`. This still allows the cosigner to verify that the initiator is valid to generate a valid musig2 partial signature, and allows for the local nonces to more closely mimic JIT behavior.
