[codex] Smoke-test the built wheel

[amarakramali]

What changed

• uninstall the editable project after building distributions
• install the generated wheel without resolving dependencies again
• run all six console-command smoke tests against that installed wheel

Why

The previous workflow built and inspected the wheel but still exercised console commands from the editable installation. A wheel with broken entry points or missing runtime modules could therefore pass CI. This change makes the smoke test cover the artifact users actually install.

Validation

• built wheel and source distribution locally
• installed the wheel with --no-deps after uninstalling the editable package
• confirmed aep_load_forecasting imports from site-packages
• python -m pytest -q — 66 passed against the installed wheel
• all six aep-* --help commands succeeded
