Subject: [PATCH] feat: resolve relative GAUGE_PYTHON_COMMAND against project
 root

Resolve relative paths in GAUGE_PYTHON_COMMAND against GAUGE_PROJECT_ROOT,
consistent with how STEP_IMPL_DIR is already resolved in util.py.

This enables setting GAUGE_PYTHON_COMMAND to paths like .venv/bin/python
or .venv\Scripts\python in python.properties without requiring an absolute path.

Fixes #485
