tabs.js: collapse stale dangling sentence in per-card actions comment (argus #728)

When I rewrote the original 'Per-card action buttons … moved into
the sticky #selection-bar (see renderSelectionBar) which appears
when the operator has at least one agent selected via the icon
click' comment to use the docs ref, I shrunk part of it but left
the second sentence as a dangling fragment glued onto the new
short ref. Collapse cleanly: docs ref + the still-useful
`needs update ↻` chip note.

 ### Selection bar
 
+Per-card action buttons (`R3ST4RT` / `ST0P` / `ST4RT` / `R3BU1LD` /
+`DESTR0Y` / `PURG3`) used to live on each container row; the
+operator picked the bulk-bar model instead. Clicking an agent's
+icon toggles its selection (an in-memory `Set<name>`); `Esc` or
+the bar's `✕ clear` button drops everything. The selection
+persists across tab switches in-memory — the bar just hides on
+non-SW4RM tabs since other tabs don't show the agent cards needed
+to cross-reference.

 When one or more agents are selected (via icon click), a sticky
 frosted-mauve bar slides up from the bottom of the viewport
