feat: Зеро-персонаж, auto-publish, auto-series, channel-stats, fallback covers

- Персонаж Зеро: 23 позы (zeroCharacter.js), скрипты генерации - Auto-publish статей в TG: multipart upload, кнопки, режим alternating Zero/cover - Fallback цепочка обложек: aiprimetech gpt-5.5 → Pollinations → local SVG (6 палитр) - Auto-series: Claude haiku определяет серию для каждой статьи автоматически - Channel stats: подписчики, история, delta 24h/7d - Photo-search: Yandex API, профили доменов, Redis лимиты - Scheduled posts runner: backfill, preview, queue, cancel - promptBuilder: author_persona Зеро, голос от первого лица - Fixes: dollar-placeholder bugs в PATCH channels/autogen, listArticles фильтры - AI model: gpt-5.5 для image generation
