Replaced the manual loop with `padStart` to simplify the code and improve readability. This aligns with modern JavaScript practices, making the function more concise and easier to maintain. No functional changesjust a cleaner, more efficient approach to padding numbers with leading zeros.

Replaced the old implementation of collapseLeadingSlashes, which iterated over each character, with a more concise and efficient version using a regular expression. The new version uses 
eplace() to collapse leading slashes into a single slash and handles empty strings by returning '/'. This update improves code readability and leverages modern JavaScript string methods.
