Setup instructions mention spaCy, but it's not a declared dependency

[parthnarkar]

While setting up the project as a new contributor, I noticed an inconsistency in the setup instructions.

The documentation recommends:

pip install -e ".[dev]"
python -m spacy download en_core_web_sm

However:

• pyproject.toml does not declare spacy as a dependency (or optional dependency).
• Running python -m spacy download en_core_web_sm after the documented installation fails with:
  No module named spacy
• I searched the repository and found that spacy is only referenced in documentation (CONTRIBUTING.md and docs/TECHNICAL_SPEC.md), not in the runtime source code.

Is the spaCy setup step still required, or should it be removed from the contributor setup instructions?
