kolaente 9d2c9d9a2d fix: resolve position conflicts in a stable order
address pr-swarm finding: grouping the conflicts by view left them in map order,
and the order is observable - resolving a lower group moves its tasks toward the
next one, so which runs first decides whether the view gets a local respace or a
full recalculation. Same data, different result per run.

Also restores the count == 0 early return dropped when that guard was split, and
lets the placement helper own the batch state so a caller cannot hand it tasks
the state was not built from.
