This is about my favorite door sill detail for concrete walls: door sill dtl | 363 HOUSE Though I would get in touch with the architect before using it and see how well it has held up. regardless of what you do there is always going to be a thermal bridge at the door sill, but that detail seems to me to be the best at minimizing it.

Also why are you running in floor heat? Yes in floor heat feels great, but for it to be effective (with toasty warm floors) you need to have a certain amount of heat loss from the building envelope. If you are building a well insulated and air sealed house then the required floor heat takes it out of the toasty warm range and into a range that is only a bit higher than air temp, and getting floors to air temp (will feel a bit cool but not cold) is easy.
