Greptile Summary

This PR performs a comprehensive code style cleanup across 18 multidevice test files by reordering includes to match Google C++ style guide and converting local includes from angle bracket syntax to quote syntax. The changes include:

• Converting all local/project includes from <path> to "path" syntax across all 18 files
• Reordering includes in each file to follow Google C++ conventions: standard library → third-party → local project includes
• Adding blank lines between include groups for improved readability
• Removing unused includes (e.g., unused torch headers in some files)

All changes are purely stylistic with zero functional impact. The PR correctly implements the include ordering standard where:

1. Standard library headers come first (<algorithm>, <iostream>, etc.)
2. Third-party headers follow (<gtest/gtest.h>, <torch/...>, etc.)
3. Local project headers last, using quote syntax ("fusion.h", "multidevice/...h", etc.)

The refactoring improves code consistency and makes the codebase easier to navigate by establishing a uniform include style across all multidevice test files.

Confidence Score: 5/5

• This PR is safe to merge with no functional risk - it contains only stylistic include ordering changes with no impact on code behavior.
• Score of 5 reflects that this is a purely stylistic refactoring with zero functional changes. All 18 files have been consistently updated to follow Google C++ include ordering guidelines. The changes are straightforward include reordering and syntax conversion (angle brackets to quotes for local includes). There is no risk of introducing bugs, breaking tests, or affecting runtime behavior. The include pattern is correct and consistent across all modified files.
• No files require special attention. All changes are consistent stylistic improvements with no functional impact.
