Development record

A single 'abcd build next' can pick an intent that a completed run already delivered: the pick excludes only intents with a run still in progress, and once the landing has merged and removed the lane's branch, a checkout whose main has not been pulled still holds the intent in planned/, so the pick starts a second run for delivered work. A series excludes what it already picked, so only the single pick is exposed. Reported by the build-next implementer (run-2610110908001704).
