Base64url encoding
Implement base64url encoding as used in JWTs and URL-safe tokens. Given a UTF-8 string `data`, return its base64url-encoded form: standard base64 but using '-' and '_' instead of '+' and '/', with all trailing '=' padding removed. An empty input encodes to an empty string.

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
