chore: update manifest.json for v1.0.0.17

The fixed TV lists are mostly long-running shows whose first_air_date is
outside ReleaseDateRangeMonths, and paging stops at the first page with no
in-range title, so only ~7 TV candidates were found (5 then dropped by
language). Add a "discover" source per media type that asks /discover for
recent titles in AllowedLanguages, sorted by popularity (1600+ TV results
for en|fr today). TV Discover defaults on, movie Discover off.

yt-dlp failures were mostly passing HTTP 403s from back-to-back requests;
the built-in fallback is sometimes only offered 360p. Retry yt-dlp once
after 15s before falling back.
