The modifier flip (⌥ copy / ⌘ move) now reflows the source board once:
a copy re-admits the dragged originals into the resting layout, standing
dimmed in place, and a move lifts them out as before. This retires
DRAG-REORDER.md's operation-blind carve-out and makes 04-interactions.md's
"originals stay" true in flight, not just at echo. The one seam is
DragSession.hiddenMembers reading the observed operation.
Consequences carried honestly: copyCards now takes its index in the
lane's full rendered space (the zones counted the originals, so the
geometry's number is the writer's number — the old neighbour remap is
deleted); resolveOperation freezes under the committed hold exactly as
propose does, fixing a real bug where a settled within-board ⌥-copy drew
the move arrangement until the echo and visibly re-shuffled. Stationary
flips still wait for the next dropUpdated (their own Backlog card).
