Wrap `from omnivoice import OmniVoice` in a try/except ImportError, setting
OmniVoice=None when absent. Add a clear runtime ImportError in load_model()
so users get an actionable message. Allows `from nodes.loader import
OmniVoiceModelLoader` to succeed outside of pytest (where conftest.py injects
the mock) while keeping all 13 tests green.

Remove OmniVoice = None fallback in nodes/loader.py so missing omnivoice
gives a clear ImportError instead of a confusing AttributeError. Restore
__init__.py to clean form without the try/except that silently swallowed
real import errors. Add omnivoice mock to conftest.py and register a
pytest plugin that prevents pytest from treating the project root as a
Package node (which would try to import __init__.py outside a package
context and fail on the relative import).

Implements OmniVoiceModelLoader with INPUT_TYPES, RETURN_TYPES, and
load_model supporting both HuggingFace auto-download and local path
sources. Adds TDD test suite and pytest infrastructure (conftest.py,
pytest.ini) to enable testing outside ComfyUI without omnivoice installed.
