/**
 * `peaks retrospective index` — the index command (list + optional fzf
 * multi-select), hoisted out of `retrospective-commands.ts` so that file
 * clears the 300 raw-line cap.
 *
 * Identical control flow: same project-root resolution, same
 * `loadRetrospectiveIndex` call, same warning normalization, the same
 * `options.pick === true` gate in the same position, the same envelope
 * field order, the same exit codes (127 for an fzf problem, 1 otherwise),
 * the same two suggestion texts, and the same single catch — which moved
 * WITH its handler and still reports the failure (no swallow, so the
 * silent-warning counters are untouched). The fzf selection block became
 * one helper and the failure envelope another, so no function here is
 * over `max-lines-per-function` or `complexity`; nothing else was
 * rewritten.
