Skill rooting the witness directory in the system temp dir

• Witness scratch dir: before the first spawn, WITNESS_DIR=$(mktemp -d "${TMPDIR:-/tmp}/cc-team-witness-{slug}.XXXXXX"), recorded as each member's scratchDir — must fail on the ROOT. ${TMPDIR} is collected long before the witness stops being the anti-fabrication anchor, and a lead that cannot read its team's witness either parks forever or synthesizes a round product it never observed. The basename here is the one the init script actually mints, so it is not what this fixture is about: the root half stands on its own.
