fix(patch): Optimize AST traversal in EquatableMacro

[2dubu]

Description

This change optimizes the EquatableMacro.expansion function by refactoring the stored property extraction logic to a single-pass AST traversal with early exit conditions. It also removes an unnecessary isStoredProperty check that duplicated an existing condition.

These changes improve code clarity and offer minor compile-time performance improvements when expanding macros, without altering runtime behavior or output.

1. Refactored property extraction loop for single-pass AST traversal
   (remove SwiftLint disable for cyclomatic_complexity)
2. Removed redundant isStoredProperty check
3. No functional behavior change; focused on performance and code clarity

How Has This Been Tested?

• Existing unit tests have been relied upon to validate that macro behavior remains unchanged
• Manually inspected that generated Equatable and Hashable conformances continue to match expectations
• Confirmed that diagnostics for unsupported closures are still emitted correctly

Minimal checklist:

• I have performed a self-review of my own code
• I have added DocC code-level documentation for any public interfaces exported by the package
• I have added unit and/or integration tests that prove my fix is effective or that my feature works

Pull Request Overview

This PR optimizes the AST traversal logic in EquatableMacro.expansion by refactoring the stored property extraction from a functional compactMap approach to an imperative loop with early exits. The changes aim to improve compile-time performance and code clarity while maintaining identical runtime behavior.

• Replaced compactMap with a for-loop and continue statements for early exits
• Consolidated closure detection logic into a single boolean expression
• Removed redundant isStoredProperty check that duplicated existing conditions

• [nitpick] The function name isClosure should be isClosure(type:) to match Swift naming conventions for functions that take parameters.

            let isClosureProperty = (binding.typeAnnotation?.type).map(isClosure) == true ||

Sorry for the repeated lint failures. I’ll make sure to run lint locally next time 🥲

awesome, thanks!
