pyproject.toml uses private _legacy build backend

[DeFiVC]

What

The pyproject.toml uses a private build backend:

build-backend = "setuptools.backends._legacy:_Backend"

setuptools.backends._legacy is a private/internal module (prefixed with _). The standard build backend is setuptools.build_meta.

Why

The _legacy backend may be removed in future setuptools versions, breaking pip install and builds.

Scope

• Change to the standard build backend

Acceptance Criteria

• Build works with standard setuptools

Technical Context

• File: pyproject.toml, line 3
