Add StderrLog field to DownloadJob and collect all stderr lines during
download. Log the captured stderr output when a download fails to help
diagnose exit code 2 errors (geo-restrictions, auth, etc.).
- Remove --no-progress from yt-dlp args that suppressed all progress output
- Add --merge-output-format when FormatString is set (container was ignored for combined formats)

- Detect DRM errors (Spotify) and fall back to YouTube Music search via ytsearch1:
- Replace type/quality selection flow with unified format list (video+audio combined)

audio-only formats offer optional video addition (skip when content is audio-only)
- Fix formatKeyboard to use format IDs as callback data instead of display labels
- Remove dead mediaTypeKeyboard function
- Fix double-close panic in readProgress (caller is sole owner of updates channel)
