feat(breaking): Smart wallet upgrade

[zhongeric]

Changelog

Breaking Changes

• Removed encodeCalls method: This method has been completely removed
• New primary entrypoint: encodeBatchedCall is now the main method for encoding call batches
  • Same parameter structure as the previous encodeCalls (accepts calls[] and options)
  • Returns the same MethodParameters object type as before
• Default revert behavior changed: The default value for shouldRevert in BatchedCallPlanner is now true, meaning batched calls will revert by default if any call fails

Added

• Added BatchedCallPlanner class to handle batched calls with revert control
• Added encodeERC7821BatchedCall method for legacy support of the ERC-7821 specification
  • Use this only if you specifically need the ERC-7821 entrypoint
  • For all other cases, use the new encodeBatchedCall method

Migration Guide

// Before:
const result = SmartWallet.encodeCalls(calls, options);

// After:
const result = SmartWallet.encodeBatchedCall(calls, options);

// For ERC-7821 specific compatibility:
const result = SmartWallet.encodeERC7821BatchedCall(calls, options);

This update simplifies the API while maintaining backward compatibility through parameter structure. The main behavioral difference is that batched calls will now revert by default when any contained call fails, improving safety by preventing partial execution of transaction batches.
