test(quick-dev): add renderer smoke test with TOML override

New test/test-quick-dev-renderer.js spins up a temp project with
base _bmad/config.toml and a _bmad/custom/config.user.toml override,
runs render.py, and asserts the override wins in rendered workflow.md
and that sprint_status is rooted at an absolute path in the temp
project. Registered as test:renderer in package.json and chained
into the npm test script.

Part of plan-quick-dev-python-config-hardening.md (F7).
