TaskId
An opaque, stable identifier for a single unit of work in the warp task scheduler.
Task IDs are the keys into the work queue (ORSet<TaskId>) and the results board (ORMap<TaskId, LWWRegister<Result>>). They travel with the work and must be stable across nodes — the same physical task must present the same value on every peer that ever sees it.
A string that names the task's content (a hash of the input, a UUID, a filename) is a natural choice.
