Replace install.py with standard requirements.txt

install.py was running arbitrary pip installs as part of node loading,
which is dangerous in a shared venv. Standard approach: requirements.txt
lists the safe deps (transformers, accelerate, soundfile, etc.);
omnivoice itself must be installed once manually with --no-deps to avoid
overwriting ComfyUI's torch. README documents this clearly.
