[WIP] Add functionality to create output file if it doesn't exist

[Copilot]

Plan: Create output file if it doesn't exist

Problem

When a user specifies an output file with -o or output: that doesn't exist, BadgeSort crashes with FileNotFoundError instead of creating the file.

Solution

Modify the file handling logic in badgesort/icons.py to:

• Check if the output file exists before trying to read it
• Create an empty file if it doesn't exist
• Append badges to the new file (since there are no markers)

Implementation Checklist

• Understand the issue and existing codebase
• Run existing tests to ensure they pass
• Write tests for non-existent file scenario
• Modify badgesort/icons.py to create file if it doesn't exist
• Run tests to verify the fix works
• Manually test the CLI with non-existent file
• Request code review
• Run security scans

Changes Made

1. Added test: test_integration_create_output_file_if_not_exists in tests/test_integration.py to verify the new behavior
2. Modified badgesort/icons.py: Added os.path.exists() check before reading the output file. If the file doesn't exist, it initializes output_content as an empty string and logs an informative message.

Testing

• All 23 tests pass (22 existing + 1 new)
• Manual CLI testing confirms file is created and badges are appended correctly
• Subsequent runs update the file as expected
