Refine .gitattributes and clean .gitignore

Improve language/statistics settings and tidy ignore rules: .gitattributes now marks *.func as detectable, excludes ct/headers/* and markdown docs from language stats, classifies generated/config files (json/lock/yml) as linguist-generated, and enforces text=auto eol=lf. .gitignore was reorganized and simplified: .vscode is explicitly preserved (!.vscode/), obsolete debug/temp entries were removed, and overly broad ignores for compiled artifacts and Git metadata were dropped to avoid accidentally hiding repository files.
