Split along the natural seam now that the file is fully covered:
_transcribe_probes.py 177 _try_import, the four dependency probes,
generate_sine_wav, prepare_model, test_cuda
transcribe_helpers.py 142 the eight _handle_* functions and main()
All 18 top-level definitions verified AST-identical to HEAD, and an AST
scan confirms neither module references a name it does not bind.
transcribe.sh is untouched - it invokes tools/transcribe_helpers.py by
path, and that path still exists with the same name and executable bit.
The CLI tests' patch targets did not move either, because main() dispatches
to names imported into its own namespace.
Verified by running every subcommand and reading the exit status directly,
since those codes are the contract transcribe.sh branches on:
python-version 0, check-faster-whisper 7, check-ctranslate2 1,
check-diarization 0, deps-installed 0; generate-wav writes the same
96044-byte WAV as before the split. 41 tests pass at 100% line and branch
on both modules; 243 pass in the directory. Over-cap files 35 -> 34.
