/**
 * SourceManager — exposes podcast sources as SettingItems for the depth-stack.
 *
 *   • "Add Source" — an editor item; drilling in shows a name/URL add form.
 *   • Each source — a toggle item (Space toggles enabled) whose display shows
 *     the source type and on/off state.
 *
 * Advanced per-API-source options (country/language/explicit) are flattened to
 * simple toggles/cycles reachable by drilling into the source's editor.
 * Movement flows through nav.action — no own useKeyboard (avoids the old
 * right-pane key conflicts).
