gnofly package

Package gnofly is the market of gnofly's planes: a fixed-price book where a plane's owner lists it, anyone buys it, and each sale pays the planes realm's royalty (RoyaltyInfo: 5% to the gnofly treasury) out of the price.

It is a wrapper, not a collection: it mints nothing. The planes are the tokens of gno.land/r/g1t2kg2vtr3fukg43eujkn6x53gfdyakhngt4sfd/gnofly/nfts/planes, moved with that realm's TransferFrom. A seller first approves this realm there (Approve for one plane, or SetApprovalForAll); List then moves the plane here, in escrow, Buy hands it to the buyer and Cancel back to the seller.

Its calls and reads have the shapes Bazaar's site (bazaar.gnomi.fun) uses on a collection package (List, UpdatePrice, Cancel, Buy, Transfer; ListOpen, ItemLine, TokensOf, Minted), so that it can be registered there later, under the slug of its last path element. It is not registered, and pays Bazaar nothing.

It is version v0 of the market (the path's v0). SetPaused stops new listings for a move to a newer one; Cancel and Buy keep working, so no plane is ever stuck here.

Every write is a direct call from a wallet: no realm can list, buy or cancel in a user's name.
