 * How much of a tool call the transcript shows. Three stops on one dial, least
 * to most, cycled with `app.view.cycleForward` / `app.view.cycleBackward`:
 *
 * - `radar` — one line per *chain*: a run of consecutive tool calls collapsed to
 *   the shape it had while working, or what it amounted to once it is over.
 * - `peek` — the tool's own call line and the first few lines of what came back.
 *   The default.
 * - `full` — the same call line with nothing trimmed away.
 *
 * There is no separate expand state. `full` *is* the expanded view, and
 * `app.tools.expand` jumps straight to it from any stop and back again — which
 * is why the dial is the only thing that has to be remembered, and why `full`
 * can finally mean full.
 *
 * This lives in core rather than next to the renderer because the settings
 * manager persists it, and core must not reach into the interactive UI.
