Add nginx-like autoindex functionality with three output formats: - HTML: styled directory listing with sortable columns - JSON: structured API-friendly output - XML: machine-readable format Configuration options: - auto_index: enable/disable directory listing - auto_index_format: output format (html/json/xml) - auto_index_localtime: use local time instead of GMT - auto_index_exact_size: show exact bytes vs human-readable Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
