The tenant runner (assembly-economics 2521955) refuses any web-fetcher other
than 0.2.0. Instead of defaulting to a moving ~/web-fetcher checkout, the
approach now uses an explicit WEB_FETCHER_PATH/ASSEMBLY_WEB_FETCHER_PATH or
keeps a shallow clone of tag v0.2.0 under ~/.cache/rein-aharness/ and refuses
it if HEAD is not exactly at the tag. Each run passes --cache to a fresh temp
directory outside the checkout; its path is reported in the hub detail.
