chore(config): improve .gitignore for Hugo project

- Add resources/_gen/ for Hugo-generated assets
- Add node_modules/ for NPM dependencies
- Add test output directories (tmp/, .htmltest/)
- Add devbox local directory (.devbox/)
- Add IDE files (VS Code, IntelliJ, Vim)
- Add OS-specific files (macOS, Windows)
- Add log files
- Remove package.json from ignore (needed for NPM scripts)
