Code Review

This pull request adds a .gitattributes file to normalize line endings across the repository and applies minor formatting and translation updates to various documentation files. The review feedback correctly points out that Windows batch files (.bat and .cmd) require CRLF line endings to execute properly, and suggests adding explicit rules for them in .gitattributes to override the global LF setting.

Important

Windows batch files (.bat and .cmd) require CRLF line endings to execute correctly in Windows environments. Since the global rule * text=auto eol=lf forces LF line endings on all text files, any batch files added to the repository will be checked out with LF line endings, which can cause syntax and execution errors on Windows. It is recommended to explicitly configure CRLF for these file extensions.

# Shell scripts must use LF
*.sh text eol=lf

# Windows batch files must use CRLF
*.bat text eol=crlf
*.cmd text eol=crlf
