- Rename python/configs/usage.md → usage-simple.md so both scripts have a
parallel runnable reference file in the same directory
- Add python/configs/usage-phases.md: runnable sh commands + real expected
output for phases.py against every error-path config, including a note on
the key difference from simple.py (HTTP 4xx exits 0 in phases.py vs 1 in
simple.py because phases.py completes at the network level)
- Update doc cross-links in docs/usage/py-simple.md and py-phases.md
