/**
 * Zero-setup Python provisioning.
 *
 * `python -m venv` does NOT install a Python — it creates a thin environment
 * that symlinks back to an existing interpreter, frozen to that interpreter's
 * version. So when the host has no supported Python (e.g. Homebrew now ships
 * 3.13/3.14 as `python3`, which has no wheels for agentscope's native deps),
 * the runner can't build a working venv no matter what.
 *
 * This module removes the requirement for a host Python entirely: it uses
 * `uv` (a single static binary) to download a *managed, standalone* CPython of
 * the supported version and returns its interpreter path. The existing venv
 * pipeline then builds from that. `uv` itself is bootstrapped from its official
 * GitHub release if it isn't already installed — no `brew install`, no manual
 * steps. All failures degrade to `null` so the caller can fall back to a clear
 * "install Python 3.12" message.
