Pull Request Overview

This PR fixes how file paths are extracted and stored in the coverage parsing functionality. Instead of using the full captured path directly, it now extracts a relative path starting from "src/" to ensure consistent path representation in coverage data.

Key Changes:

• Modified path processing to extract relative paths starting from "src/"
• Added fallback logic to use the full path if "src/" is not found
• Updated both the current_file assignment and coverage_data insertion to use the processed relative path
