…math Adds proptest as a dev-dependency and a new test_proptest.rs module with 7 invariants run over 1 000 cases each: supply ≥ borrow, net equity equals initial, geometric-series bound, HF monotonicity, compute_step supply equals balance, final borrow is zero, and no panic on extreme i128 inputs. Closes Dgetsylver#50 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
Implements issue #50 — D9: Property / invariant tests for leverage math.
Cargo.toml: addsproptest = "1"to dev-dependencies.src/test_proptest.rswithProptestConfig::with_cases(1_000)— seven invariants:total_supply >= total_borrow(borrow never exceeds supply)total_supply - total_borrow == initial(net equity preserved)total_supply <= initial / (1 − c)(geometric-series upper bound)c_factor(higher c → strictly higher HF)compute_stepsupply leg always equalsbalancecompute_stepfinal borrow is exactly 0checked_mul)Test plan
cargo test -p blend_leverage_strategy— proptest runs 1 000 cases per property, all pass.Closes #50
