Notes

• Read-only tools (get_reserve_data, get_user_account, get_user_reserve) work without PRIVATE_KEY
• Write tools (supply, borrow, repay, withdraw) require PRIVATE_KEY
• Approvals are checked before sending — no redundant approval transactions
• Max repay/withdraw uses type(uint256).max — Aave caps at actual balance/debt
• Health factor warnings trigger below 1.5 (liquidation threshold is 1.0)
