swarmexec v1.16.2 — states you can read off the screen

Two reports from testing, both the same shape: something you can toggle, with
no way to see which way it was set.

- The log footer names the follow state instead of just the key. It read
  "follow on/off" whatever the view was doing, and that is the one place you
  look to find out — a view with follow switched off looks exactly like a
  container that has gone quiet. The active half is now marked, in colour and
  underlined, and it repaints on the toggle.
- The inspect overlay has a tab strip. It has held three views for a while —
  the tabular summary, live resource usage, and the raw daemon JSON — but the
  only place any of them was named was a footer hint for whichever came NEXT.
  So the resource-usage view was reachable and undiscoverable at once: you had
  to press "t" twice to find it, past a hint that said "raw json", which is
  something else. The three are now named up front, in the same shape as the
  main window's tabs.
- The digits select a view directly — 1 table, 2 stats, 3 raw json — and "t"
  still cycles. The help overlay lists both.
- Documentation follows in all five languages. It also corrects a sentence that
  was wrong before this release and would have been plainly wrong after it: the
  service edit keys are in the overlay's footer, not its title.
