Pull Request Overview

This PR adds smart defaults and template variable support for token addresses in BalanceNode, implements comprehensive test cases for JavaScript find() expressions in Branch nodes, and introduces a complete Uniswap V3 contract interaction test demonstrating tuple parameter handling.

• Enhances BalanceNode to intelligently extract addresses from token objects and automatically enable zero balance inclusion for specific token requests
• Adds extensive test coverage for Branch node JavaScript expressions including case-sensitive address comparisons and numeric conversions
• Creates comprehensive Uniswap V3 integration test with detailed documentation on ERC20 state overrides
