chore(gitattributes): enhance file handling and language detection

Expand the .gitattributes file to improve language detection,
line ending normalization, and merge strategies. This change
adds support for various file types, ensuring they are correctly
identified and processed by Git and GitHub linguist. It also
defines binary files, sets merge strategies for specific file
types, and specifies files to be ignored during export. This
enhancement aims to streamline development workflows, improve
cross-platform compatibility, and ensure consistent handling of
files across different environments.
