docs: record the operation-feedback state before the v2.10.0 cut

Plan checkboxes stood at zero although P0, A, B, C1 and D are all merged --
anyone reading it would have assumed nothing was built. Ticks the merged
packages, records A5's cancellation and the visual pass, and names the two
leftovers (the three unused ops.* keys from A3/A4, C2-C5 as the only open
group). Also corrects the batch_* tool count from eight to seven and puts the
OperationTiming kill-switch note in the Ui CLAUDE.md back into English.
