Continues #3901 (dashboard/#3906, agent+swarm-ui/#3917, this closes out
the packages/shared slice — jobq-graph was already done separately).
Scanned the rest of shared/src for the same 'used to be X, now Y'
pattern: one real hit. The other two matches (hive-btn.js's is=
attribute history, hive-side-panel.js's one-word /* legacy */ comment)
are load-bearing or too trivial to touch.
