Breaking changes (event model)

Move events are now idempotent
move.node, close.issue, and reopen.issue now persist { parent, rank }
The previous { pos } (relative positioning) has been removed

All node creation events now require rank

init.workspace, add.workspace, add.board, add.swimlane, add.issue, add.field

Existing logs using pos or missing rank will fail to load

Reinitialize or manually migrate data
