Add Support for Fuzzy Matching

[aliviahossain]

Problem: The bot may fail to recognize a question if the user makes a simple typo (e.g., "how can i registar?").

Suggestion: Before processing the input, use a library like thefuzz (or a similar fuzzy string matching algorithm) to correct potential typos or match the user's query to the closest "pattern" in intents.json.

PLEASE ASSIGN ME THIS ISSUE UNDER THE GSSOC' 25 LABEL.
