Adds yield-generating capability for idle stablecoins (USDC/USDT/DAI)
on Ethereum and Base via Aave V3 and Morpho Blue vaults, using the
existing Safe multisig proposal flow for governance.
New lib files: yield-protocols (constants/ABIs), yield-rates (DeFi Llama
+ Morpho GraphQL with 5min cache), yield-positions (on-chain queries),
yield-tx-builder (MultiSend calldata for Safe proposals),
yield-strategy (idle detection + allocation suggestions).
5 API routes, "Yield" view tab with rates table, position cards, and
advisory strategy suggestions. Zero new dependencies.
