- python/configs/: 7 purpose-built config files, one per error class:
all-ok.txt, dns-failure.txt, connection-refused.txt, timeout.txt,
tls-errors.txt (badssl.com), http-errors.txt (real 404 paths on stable
hosts), mixed.txt (one of each, no timeout)
- python/configs/usage.md: runnable sh commands + expected output per config,
plus quick-sweep and full-sweep loops; commands written for running from
the python/ directory
- docs/custom-usage-examples.md: example 11 added (all failure classes at once)
- docs/usage/py-simple.md: added pointer to python/configs/ and corrected
limitation note (4xx/5xx are FAIL, not OK)

Probe multiple URLs in parallel with a bounded worker pool; the N samples
of each URL remain sequential to preserve accurate min/avg/max statistics.
Default auto-concurrency is min(numURLs, 8); -c 1 restores serial mode.
Output is always buffered and printed in original input order. Verified
clean with go test -race.

Examples 1-3: clean global sweep (single, 10 samples, JSON).
Examples 4-8: one failure type each (DNS, refused, timeout, HTTP, TLS).
Example 9: full matrix, all 5 failure types in one run.
Example 10: quick smoke test (-n 1, JSON, --timeout 2s, all types).
Includes runtime estimates and jq filter snippets.
