refactor(p1): optimize loop gas usage and storage reads in BasketHandler

[forumevi]

Summary

Optimized gas consumption in BasketHandlerP1.sol during historical basket iteration and search operations:

• Storage Read (SLOAD) Caching: Cached b.erc20s.length and basketNonces.length into stack/memory variables inside nested loops to minimize repeated SLOAD operations.
• Unchecked Increments: Applied unchecked { ++i; }, ++j, and ++k on bounded loop iterators to eliminate redundant overflow checks during execution.

Verification

All existing complex basket scenario tests (test/scenario/ComplexBasket.test.ts) passed successfully without breaking state integrity.

Summary by CodeRabbit

• Style
  • Added trailing whitespace formatting at the end of the contract file.
