/**
 * Codex verbosity normalization — `normalizeCodexVerbosity`.
 *
 * GPT-5 verbosity is `verbosity` on Chat Completions and `text.verbosity` on the Responses
 * API. The CodexExecutor allowlist drops `text`, so translated requests lose the hint. These
 * tests pin the fold into a single validated `text:{verbosity}` (or its removal when invalid),
 * which — paired with `text` added to the allowlist — lets verbosity reach the Codex backend.
