captchaforge 0.2.36

#!/usr/bin/env python3
"""Generate a captchaforge LOCAL scorecard (no live WAFs).

Reads the deterministic state of the workspace:
- captchaforge solver chain composition (number of solvers in default_chain)
- bench fixture registry (count + per-vendor coverage)
- challenge crate ChallengeFingerprint variants
- community.toml rule count
- test-suite counts (estimated from cargo test --list)

Outputs scorecard/local.json — a structured snapshot of what
captchaforge DEMONSTRABLY does on this machine, with no live WAF
calls. Pairs with tools/scorecard.py to inject README badges
reflecting the local-bench numbers.

This is NOT the real-WAF scorecard (that comes from
.github/workflows/scorecard.yml against production endpoints).
This is the "what does the code structurally cover" snapshot —
gives operators a starting baseline without needing network keys.
