URL to Lowercase

Convert URLs to lowercase with optional duplicate removal.

Convert all URLs in a list to lowercase to ensure consistency and avoid duplicate content caused by case differences. Uppercase and mixed-case URLs are treated as different pages by some servers, leading to unintended duplicates in crawl data. Optional deduplication removes URLs that become identical after lowercasing. Essential when cleaning up URL lists from crawlers or CMS exports.
