Rename InferenceSystem package from `src` to a unique name for cross-project imports

[akashmjn]

Context

The repo will have multiple Python projects needing to share code:

orcahello/
├── InferenceSystem/        # inference model + audio processing
│   └── src/
│       └── model/
│           └── audio_frontend.py   ← other projects need this
├── ModelDevelopment/
│   └── dataset-toolkit/    # fine-tuning data pipeline
│       └── src/
│           └── build_dataset.py    ← needs to import audio_frontend

In this example, dataset-toolkit needs to import the audio frontend from InferenceSystem (resampling, downmix, mel spectrogram) to ensure preprocessing parity between dataset creation and inference.

Problem

InferenceSystem uses src/ as a top-level Python package directory. It also doesn't have an __init__.py file, getting treated as a namespace package.

If dataset-toolkit depends on InferenceSystem as a uv path dependency, both src/ trees end up on sys.path and collide — Python can only resolve one src package. In theory working with namespace packages named as src everywhere can work around by merging both src/ trees, but this is fragile.

The root cause is that src is not a meaningfully named self-contained package.

Proposal

Rename InferenceSystem's package directory to give it a unique importable identity:

InferenceSystem/
    src/                          →  orcahello_inference/
                                       __init__.py
        model/                         model/
            __init__.py                    __init__.py
            inference.py                   inference.py
            audio_frontend.py              audio_frontend.py
            types.py                       types.py
        orcasound_hls/                 orcasound_hls/
            ...                            ...

With hatch config:

[tool.hatch.build.targets.wheel]
packages = ["orcahello_inference"]

Desired import structure after rename

# In any project that depends on inference package (clear provenance):
from orcahello_inference.model import OrcaHelloSRKWDetectorV1
from orcahello_inference.model.audio_frontend import load_processed_waveform
from orcahello_inference.model.types import DetectorInferenceConfig

# Local code within another project (no collision):
from src.build_dataset import build_recording_dataset

No namespace package tricks needed — each package has a unique name.

Scope

• Rename InferenceSystem/src/ → InferenceSystem/orcahello_inference/ and add __init__.py to avoid it being a namespace package
• Update all internal imports (from src.model → from orcahello_inference.model)
• Update scripts/, tests/, LiveInferenceOrchestrator.py, Dockerfile
• Update any downstream consumers
