Process killed when input is a very long file.

When I do:
`poetry run python -m examples.generate_webvtt -i ~//segment.wav -m vosk-model-en-us-0.22-lgraph`
it works just fine but when i try to run it with the complete file (1.5 hours) it outputs that the process had been killed.

The segment.wav file is 1.5 minutes.

I tried to delete the transcription part (I only need the speaking diarization) and the same problem occurs.

Is the maximum size or length of the file defined somewhere?

Start at the examples.generate_webvtt entry point and reproduce the process termination with the 1.5-minute and 1.5-hour WAV inputs using the command in the report. Trace where input duration or resource use is handled; done means identifying whether a maximum exists and documenting the supported behavior for long files.
