ctranslate2 <=4.4.0 marks its native library's stack RWE; kernels that
refuse the request fail the dlopen, taking whisperx, faster-whisper and
Argos translation down. main learned to detect and fall back; this also
fixes the library: core.execstack clears the one ELF bit in place on
first probe (Linux-only, memoized, never raises), so the engines load
normally on hardened kernels. Argos's probe moves to
argostranslate.translate so it cannot advertise an engine whose every
request 500s, and the dub route returns one actionable 400.
Also: pytorch-whisper survives a CUDA OOM at transcribe time by
stepping the batch down (16->4->1, 8->2->1 with word timestamps) and
finishing on CPU rather than dropping the chunk.
