/**
 * gen-voice handler — Minimax TTS via ab-api unified /tool/tts (provider=minimax).
 *
 * Operations:
 *   --list-voices true                 → GET available voice IDs from /voice/page (live)
 *   --list-voices true --local true    → print the built-in language-tagged
 *                                        fallback catalog (offline, no API call).
 *                                        **CLI-only escape hatch for offline dev.**
 *   default                            → synthesize text into an MP3 URL
 *
 * `local` is deliberately absent from `skills/gen-voice/skill.json`'s
 * `parameters`, which is what ab-agent turns into the model-facing tool schema.
 * A model asked to check a voice id would reach for `local: true`, get a
 * two-entry hardcoded list back, and conclude that a perfectly valid voice does
 * not exist — which is exactly what happened on the hosted web agent
 * ("本地回退列表中没有该音色"). The remote catalog is the only authority on
 * which voices exist; the local list is a developer convenience for working
 * without a token, and it is only reachable by typing the flag yourself.
 *
 * The previous Python script also offered `--download` to write the MP3 to
 * disk. That's intentionally dropped here: the agent flow never used it (the
 * audio URL is persisted in cloud) and removing local file I/O keeps the
 * handler stateless.
