ci: upload cli docs artifact for release

The skills feature was removed in this PR but build.ts still emits bundled docs into packages/cli/docs/ (listed in package.json "files"). The Release job doesn't rebuild cli, so the docs need the same upload/download artifact roundtrip the old skills directory had.
