"""A skill export must not ship a venv.

Reported by Haik Decie: exporting a skill with a Python venv failed on a secret-shaped value inside
`.venv/.../packaging/licenses/_spdx.py`. Two stacked bugs; this pins the root cause. The walker
bound `dirs` and never pruned it, so it swept a python3.13 tree with absolute paths baked in, dead
on any other machine, into the bundle. The app exporter has always pruned the same set.
