[Copilot]

build-pipeline.yml was failing before lint/tests ran because pip install .[dev] triggered setuptools package discovery on a flat repo layout (web, workflow, more_math) and aborted wheel metadata generation. This PR adjusts CI setup so dependency installation does not require building the local package.

• Root cause addressed

  • Remove editable/local package installation path that invokes setuptools auto-discovery during CI bootstrap.

• Workflow changes

  • Update Install dependencies in .github/workflows/build-pipeline.yml:
    • Keep python -m pip install --upgrade pip
    • Install runtime deps from requirements.txt
    • Install CI tools (pytest, ruff) explicitly

• Net effect

  • CI environment provisioning no longer depends on packaging metadata resolution, allowing the pipeline to reach lint and test steps.
