YouTube's SABR-only streaming rollout produces errors like "Signature
solving failed" / "Requested format is not available" that don't
mention cookies, so the existing no-cookies fallback never triggered.
Cookies also disable the android client, which is often the only one
still returning usable formats under this restriction.

EXTRACTOR_ARGS used ':' instead of ';' between player_client and skip
fields, so yt-dlp parsed "android:skip=translated_subs" and "hls" as
bogus player_client values and silently fell back to the web client
only, which fails the n-challenge and returns no formats.
--max-requests=1 fully restarted the gunicorn worker after every
single request, opening a race window that could drop the response
connection right after a successful download; raised to 20 with
jitter to keep the periodic-recycle safety net without doing it on
every request.
reply_video() to Telegram had no retry, so a transient httpx
transport error during upload discarded an already-downloaded video;
added the same 3-attempt retry pattern already used for the
downloader services.
- Замена reply_video() на reply_document() в bot.py — Telegram больше не сжимает видео
- Исправление format_id в get_youtube_formats(): конкретные format codes + fallback best[height<=N]
- Замена bestvideo[height<=N]+bestaudio на best[height<=N] — гарантированно работает когда
YouTube не отдаёт отдельные video-only потоки для низких разрешений
- Добавлено логирование реально скачанного формата для диагностики
- Разделение на микросервисы: youtube-downloader, instagram-downloader, vk-downloader
- Основной бот в корне проекта, работает через HTTP API с сервисами
- Каждый сервис запускается отдельно в своей папке
- Видео сохраняются в папке video/ и не удаляются
- Обновлена документация и архитектура
- Скрипты для Instagram cookies перенесены в instagram-downloader/
