Update .gitignore to include scripts for loading environment variables and Git credentials. Remove obsolete documentation files including 100_PERCENT_LINK_VERIFICATION_ACHIEVED.md, CROSS_REFERENCE_VERIFICATION_REPORT.md, DOCUMENT_RELATIONSHIP_VISUALIZATION.md, and several project management reports to streamline the repository and enhance maintainability. Revise DOCUMENT_RELATIONSHIP_MAP.md to correct link paths and add a new section for visual specifications.
