Fix: Standardize pyproject.toml and update CI to use pip

- Corrected the `[project.dependencies]` syntax in `pyproject.toml` to be a valid empty array, resolving the CI error.
- Updated the `.github/workflows/ci-cd.yml` to remove Poetry and use a standard `pip` and `build` based workflow.
- Replaced `poetry install` with `pip install -e .[dev]`.
- Replaced `poetry build` with `python -m build`.
- Adjusted the CI caching mechanism to work with `pip` instead of Poetry.

This completes the migration to a fully PEP-compliant packaging setup and ensures the CI pipeline is aligned with the new tooling.
