EcoPulse v2.2.0 — Quality, Docs and CI

What is New in v2.2.0

Bug Fix

• Fuzzy Black-Scholes crash on Windows CI: numpy and scipy were missing from requirements.txt. FuzzyBlackScholes._bs_call() calls scipy.stats.norm.cdf.

Quality

• Smoke tests now construct all 12 quantitative page builders and verify they return non-null widgets.
• CI workflow triggers on pull_request to main, not just tags, so every PR is validated on Windows.

Documentation

• README updated with a quantitative engine table documenting all 12 pages and 40+ models.
• CHANGELOG entries for v2.1.0 and v2.2.0.
• quant_pages.py docstring fixed (said "Three" — now correctly says "Twelve").
