Follow-up to #3, which merged before this landed on the branch.

+171 agents with no recorded activity sat between main and the first agent row, every frame — a census of things that did nothing, directly on top of the one thing that was doing something. §1.5 asks that they be stated, not that they be stated first.

The footer carries the count now, which is where the pane's other chrome lives:

j/k move · ⏎ open · a returned · ? keys      171 quiet · s lists

s opens the census — the full list with each agent's id, type, spawn and last event, the same view ⏎ on the old line reached. s for suppressed, which is what the code and the docs call them; "quiet" is only what the footer has room for.

The count outranks the right column's mode hint, which is a reminder of a key ? also lists, where this is a fact about the session stated nowhere else on the screen. It never outranks an ask, a disconnect, or the scroll position.

That retires the inline expansion (quietLines, quietPreview): selecting the line used to grow six names under it, a worse copy of the census the same keypress opens. quietDetail stays — the idle screen still expands its own count, and the condensed screen still carries a line, because neither has a footer to put it in. Under 40 columns it still rides on the header as AGENTS 5 +40.

Second commit drops quietLineDrawn, dead since selectableIDs started reading the frame's hit-test metadata, and whose doc comment this change makes untrue.

Full suite passes; the three codexsrc failures are pre-existing on main.
