lnurl-mint >= 0.4 refuses a mint quote without comment=sha256(secret) and
keys the note by that secret instead of the payment preimage. prepareMint
detects the capability per mint (commentAllowed >= 64 or mintToHash),
binds the quote to a wallet-drawn secret, and claimMintedNote polls the
note itself - no preimage, no rotate, since the secret never rode an
invoice. Mints that never advertised the capability get the byte-identical
old request and stay on the preimage path; a mint that took the hash but
credited the preimage is caught by the claim poll and rescued through the
quote's verify URL. The d.ts augments the conformance package's stale
published declarations for its comment-naming flags.
