Subject: [PATCH] Refactor YieldNest fee adapter and update chains

Simplifies the fee calculation logic by aggregating all tokens received by the fee collector and updates the supported chains to include Ethereum, Base, and BSC. Also updates the adapter to version 2 and revises the methodology for fee and revenue reporting.
