"""Shared test fixtures.

Isolate the persistent browser-skill store (and metrics) into throwaway temp
dirs for the whole test session, so tests never write skills/metrics into the
real ~/Library/Application Support/OpenSwarm/data tree (which would pollute the
dev machine and let a stale persisted skill leak across test runs).
