closes #396
Summary
This PR adds a new Soroban lending/borrowing contract under examples/lending.
Changes include:
Single-reserve lending pool implementation.
Deposit and withdrawal support for liquidity providers.
Collateral deposit and withdrawal flows.
Borrow and repay functionality.
Utilization-based interest accrual.
Scaled balance accounting with supply and borrow indexes.
Collateral health checks and pool liquidity checks.
Focused tests for lending, borrowing, repayment, interest accrual, and validation.
Reason
This implements the MVP-critical lending/borrowing contract feature requested in issue #396, enabling users to supply assets, borrow against collateral, and accrue interest over time.
