Local Dev 5cbf9e38e5 registrar: build and send a release, and keep registration closed until it confirms 
buildReleaseTx spends the certificate and writes no token output: the
omission is the burn. The certificate's own dust pays the beacon and the fee,
so a release needs no other coin.

releaseWithBuiltInWallet checks whether the certificate sits in a beacon
transaction. One that arrived by a plain transfer cannot be proven burned
from the beacon history, so the flow publishes an UPD first and releases its
output. Both paths ran on chipnet, and a released name was registered again
after its release confirmed.

checkAvailability now reports a pending release as not available: a REG
broadcast while the release is unconfirmed could be mined beside it and be
void, and the buyer would have paid for nothing.
