feat(todo): carry the parallel-active count through ToolRow's summarySuffix

Rebuild the todo row's parallel summary on the shared ToolRow that master
introduced: planSummary still returns the active name and the remaining
count separately, and the row hands the count to a new non-shrinking
summarySuffix slot so a narrow row clips the summary text before the count.
An error row drops the suffix, whose collapsed summary is the failure line.

Re-record the ACP todo-write transcript for the parallel prompt, regenerate
the config catalog for the required allowParallelInProgress field, and
re-record the bilingual pairing hashes.
