A paused engine with nothing running derived executorState "idle", so the
footer badge was indistinguishable from a healthy engine waiting for work.
That is exactly the state a pause settles into once in-flight tasks drain:
triage and planning stall while the board keeps moving, with the pause only
visible by opening the Engine Control menu. Pause state now dominates run
state; the adjacent counters still report throughput.
In the CLI TUI, the global `t` (Git view) branch returned before the Utilities
dispatch in the same key handler, so the advertised "[t] Toggle Engine Pause"
was unreachable dead UI. It now yields when Utilities owns input, and because
the shortcut can stop the board, pausing takes a second `t` within 5s while
resuming stays single-press.
Tests assert the invariant across the whole state matrix (both pause flags x
0/1/5 running), not just the zero-running repro, plus the TUI routing, the
two-press pause, single-press resume, and re-arm behavior.
