🛠️Normalize test line endings

Line Endings Normalization in Fixture Tests

Description

Added line endings normalization to fixture tests to ensure consistent comparison between expected and actual outputs across different operating systems.

Problem

Test fixtures could fail when run on different operating systems (particularly Windows vs Unix-based systems) due to inconsistent line endings (\r\n vs \n). This caused false negatives in the test suite when the only difference was the line ending style.

Solution

Added a normalizeLineEndings function that converts all Windows-style line endings (\r\n) to Unix-style (\n) before comparing test outputs. This ensures that:

• Tests are reliable across all operating systems
• Git's automatic line ending conversion doesn't affect test results
• We're testing the actual content formatting rather than platform-specific line endings

Testing

• Verified tests pass on both Windows and Unix-based systems
• Confirmed that the normalization doesn't affect the actual plugin output
• Existing test cases remain unchanged in their assertions
