Draws

Seal the draw

Freezes the entry list: picks a future drand round, renders the canonical v2 list file (the round is in the header, so one SHA-256 binds list and round), pushes it to the public proofdraw/draw-lists git mirror, and submits the hash to an OpenTimestamps calendar. The commit must land at least 10 s before the round publishes or the seal aborts. With wait: true, holds the connection until the round arrives and returns the resolved draw (bounded by the server's wait cap, default 60 s).
