YouTube-side changes had broken playback entirely. Fixes:
- Apply the remote signature cipher independently of OAuth. Deciphering and
authentication are unrelated, but the cipher was only configured when OAuth
was enabled, so the default install fell back to the bundled extractor and
failed with "Must find sig function from script: /s/player/<id>/...".
Now always applied, and configurable via playback.youtube.remoteCipher.url.
- Add the ANDROID client and order the client list by reliability. ANDROID is
currently the only client YouTube reliably streams to anonymously. WEB moves
last, as YouTube answers it with SABR-only responses carrying no playable
format ("No supported audio streams available, available types:").
- Detect sign-in failures across the whole exception graph. The existing hint
could never fire: it matched the aggregate AllClientsFailedException message
rather than the per-client reasons, and compared against an ASCII apostrophe
while YouTube sends U+2019.
- Track youtube-source past 1.18.2, which predates the TV client User-Agent fix
and the contentLength recovery fix.
Measured on previously failing tracks: 5/5 playing, stable across repeat runs
(was 1/5). No OAuth required. Adds 17 tests; 676 unit + 48 integration pass.
