The tools' text filter generalizes into the browser-wide row lens: a
shared RowToolbar (input plus an optional control group) now filters
the four message categories too — user, inject, assistant, and tool
results — matching each row's tag and preview text exactly as shown
(call breadcrumbs and call-args summaries included; full bodies stay
out of scope, they load on demand).
The node-list branch splits into a derive pass (each row's tag +
preview facts, computed once) and a filtered render pass, and the
query is a lens on the OPEN category: opening a different one resets
it while step picks keep it. System stays searchless (one row) and
sort stays tools-only (reading order is meaningful for messages).
