/**
 * ActionBar — page-top action strip primitive.
 *
 * A horizontal flexbox row with three optional slots:
 *   - Search input (flex-1, grows to fill)
 *   - Filter icon button (next to search)
 *   - Primary action button (right-aligned)
 *
 * Returns `null` when no props are provided — don't render an empty
 * bar. Used standalone or composed inside `<PageShell>` (Brief #5).
 *
 * @example
 *   <ActionBar
 *     search={{ placeholder: "Search projects…", value: q, onChange: setQ }}
 *     primaryAction={{ label: "New project", icon: Plus, onClick: openModal }}
 *   />
