I have no idea what kinda tires Zipp440's may be.

Any reputable outlet that sells 'em should be able to answer your question.

Are they sold as tubeless tires? Do they have beads on the edges (either wire or something like Kevlar that can be folded)?

Truly tubeless tires aren't meant to be glued to the rims they're mounted on, they must fit rims made to mount tubeless tires of a specific size, and the rims themselves must be rated "tubeless compatible" to then be built up into wheels with this ultimate use in mind.

Tubular tires are meant to be glued to the rims they're mounted on.

This doesn't mean clincher tires with tubes inside, it means tires that have their edges (where the beads would otherwise be if they weren't tubulars) stitched together so the tire itself forms a 'tube' with the pressure-retaining bladder – tube by another name – held inslde.

The tube's inside the tire, which has its edges sewn tightly together, with bias tape and glue on the stitched-up seam that then gets glued to the outer surface of the rim that makes it a complete wheel.

"Tubeless" tires can still have tubes inside 'em, lots of folks run 'em that way. But there's no need for glue when it comes to mounting them onto rims meant to carry them. Running a tube in a 'tubeless' tire's strictly a personal preference depending on the conditions where they're intended to be used. Putting tubes in tubeless tires is kind of an insurance policy that gives the user an edge over potential flats that could otherwise ruin a fine afternoon's outing.
