func Slugify ¶
Slugify converts an arbitrary string into a DNS-safe label (RFC 1123).
The transformation:
- Converts to lowercase
- Replaces any character not in [a-z0-9-] with a hyphen
- Collapses consecutive hyphens into a single hyphen
- Strips leading and trailing hyphens
- Truncates to 63 characters (the DNS label limit)
- Strips any trailing hyphen introduced by truncation
Returns an empty string if the input is empty or contains no valid characters.
