every transcription on this machine failed with "Language detection failed
(400)" before it started. the server was fine — it had answered /inference
correctly minutes earlier — and the platform was fine. the plugin's FIRST
call sends detect_language=true, which is a whisper.cpp parameter, and
whisperx answers 400 to it.
so a pass that exists to HELP became the only thing that could fail, on a
backend that does its own detection anyway. whisperx logs "No language
specified, language will be detected for each audio file" and gets it
right per file.
a backend refusing that request is telling us it detects for itself. skip
the pass, send no `language`, and read back whatever the transcription
reports. the two-pass path is untouched for whisper.cpp, which needs it,
and the spoken-language tie-break still applies wherever detection runs.
no prompt priming when the language is unknown either — TRANSCRIPT_PROMPTS
is keyed by language, and priming with the wrong one is worse than not
priming.
