Pull Request Overview

This PR implements fee and volume tracking adapters for the Boson Protocol across multiple chains (Polygon, Ethereum, Base, Arbitrum, and Optimism). The implementation tracks daily volume through three sources: funds encumbered in exchanges, newly created offers, and newly reserved ranges for unlimited offers. The fees adapter tracks protocol fees collected from trades.

• Adds volume tracking that aggregates encumbered funds, new offer values, and reserved range allocations
• Implements fee collection tracking from protocol-charged trading fees
• Supports multiple event schema versions (v2.0.0 through v2.5.0) to handle protocol upgrades

DEX adapter was removed based on convo in DefiLlama#4884

They plan to add RWA category soon, so the offers part can then be resubmitted in the correct RWA dimension.
