Reverts 6a635d3c's piecewise depth-shift in test_recursive_crawl.py
plus matching test_cli_add tagged-URL, test_api_v1_cli_workflow,
test_config_MAX_limits assertions. Direct URLs land at snapshot.depth=0
and max_depth==depth as the single user-facing contract; only stdin/
import text adds the +1 hop for the synthetic archivebox://internal
root.
