/**
 * Adding tickers the app does not have yet (`gloomberb/tickers`).
 *
 * A pane that resolves symbols a user (or a model) named has to turn a search
 * result into a saved ticker exactly as the command bar does: the same symbol
 * and exchange normalization, the same broker contract identity, the same
 * "already saved" rule. Doing it by hand produces near-duplicates the rest of
 * the app then disagrees about.
 *
 * It is a shared host module: the repository and the event bus are the running
 * app's, and a bundled copy would write into a store nothing else reads.
 *
 * Compatibility commitment: see the note in `./utils.ts`.
