Drop the modules/threads tabs; show both as collapsible sidebar
groups mirroring the hooks UX: a handful of top picks plus a
browse popover for the rest. Default threads to collapsed.
Revert the eager re-analysis of persisted modules on attach; keep
disassembly analysis lazy and add a per-module Analyze action and
status indicator instead.
Share one sidebar-row and one browser-popover component across
hooks, modules, and threads in both the SwiftUI and GTK frontends.
