/**
 * Tests for multi-runtime selection in the interactive installer prompt.
 * Verifies that promptRuntime accepts comma-separated, space-separated,
 * and single-choice inputs, deduplicates, and falls back to claude.
 * See issue #1281.
 *
 * Per CONTRIBUTING.md "no-source-grep" testing standard, prompt + parser
 * behavior is asserted via the install module's exported pure functions
 * (`runtimeMap`, `allRuntimes`, `parseRuntimeInput`, `buildRuntimePromptText`)
 * instead of regexing bin/install.js source text.
 *
 * #1928: Google sunset Gemini CLI (2026-06-18) and the `gemini` runtime was
 * removed from GSD (Antigravity CLI is the successor). The runtime option
 * numbering below is renumbered accordingly — option 9 (formerly gemini) is
 * now hermes, and the "All" shortcut moved from 17 to 16.
 *
 * #1925: ZCode (Z.ai) added as option 16; the "All" shortcut moved from 16 to 17.
