Greptile Summary

This PR standardizes include directives across 14 multidevice test files to follow Google C++ style guidelines. Changes include:

• Converting local project includes from angle bracket style (<header.h>) to quote style ("header.h")
• Reordering includes into three groups with blank line separators: (1) system/standard library headers, (2) third-party headers like gtest, (3) local project headers
• Removing an unused torch include from test_multidevice_pipeline.cpp
• Adding blank lines between include groups where missing

All changes are purely organizational and do not modify any functional code. The includes remain correctly ordered per the project's .clang-format configuration which has SortIncludes: true enabled, ensuring automated formatting consistency.

Confidence Score: 5/5

• This PR is safe to merge with no functional risk - it only reorders includes and changes bracket style.
• Score of 5 reflects that this PR makes purely organizational changes to include directives with zero functional impact. All 14 files follow identical patterns: converting to Google C++ style with proper grouping and blank line separators. The removal of the unused torch include has been verified as safe. No code logic, behavior, or dependencies are affected. Changes align with the project's clang-format configuration.
• No files require special attention
