- Added smart treasury functionality to allocate unstreamed grant reserves into yield-bearing assets (e.g. BENJI or other Soroban lending protocols) - Separates "Principal" (owed to grantees) from "Accrued Yield" - Enforces strict liquidity safety: always maintains enough liquid assets to cover the next 30 days of streaming obligations (+ buffer) - DAO-controlled allocation with configurable percentage limit - Added harvest_yield, emergency_withdraw_principal, and reserve status functions - Prevents over-allocation that could jeopardize grant streaming commitments Closes Grant-Stream#181

- Added automated minting of "Stellar-Native Completion Certificate" NFT when a grant reaches 100% payout
- Certificate serves as permanent on-chain proof of successful delivery ("On-Chain Resume")
- NFT metadata includes: Grant ID, DAO, Grantee, Completion date, Total streamed amount, Repo URL, and description
- Integrated minting trigger into grant completion flow (`finish_stream` / full payout)
- Created separate `CertificateMinter` contract for better modularity and reusability
- Emits `certificate_minted` event for easy frontend indexing
Closes Grant-Stream#148 Grant-Stream#105

Description
This PR implements Issue #182 - Add LP_Token_Staking_as_Grant_Collateral.
Overview
To create deeper economic alignment, grantees can now stake Liquidity Provider (LP) tokens (from Stellar DEX pools) as collateral for their grants.
This mechanism strongly incentivizes grantees to actively support and maintain the project's token liquidity.
