fix: withhold unsound Lean certificates; certify d/dx sin (B3) (#221) * fix: withhold unsound Lean certificates and certify d/dx sin (B3) Integration logs no longer emit false `integrand = F` equalities; chain-rule and unfinished diffs return no certificate instead of `sorry`. Simple unary diffs use Mathlib `Real.deriv_*` tactics, and algebraic cleanup stays a plain equality. Add `diff_sin` to the strict Lean CI corpus.

fix: sum Faulhaber/geometric, solve numeric fallback, README (B4–B6) (#220) * fix: Faulhaber/geometric sums, solve(numeric=True) fallback, README diff (B4–B6) Gosper Gaussian elimination aborted on free (zero) columns, so Σk failed; also teach ratio extraction negative powers and c^k. When Lex back-substitution hits degree > 2, numeric=True falls back to homotopy. Correct the quickstart diff comment that dropped +1 inside cos.
