Fix/improves eliza fallback responses

[Aman-Baliyan]

Fixes #57

This pr improves fallback responses when the chatbot cannot answer a question. Replaces unhelpful Eliza responses (e.g., "Why do you ask?", "Does that question interest you?") with clearer messages that acknowledge uncertainty and guide users.

Updated the Eliza script (src/main/resources/eliza/script) to replace generic fallback phrases with user-friendly messages that: 1.Acknowledge when the bot doesn't have an answer 2.Suggest rephrasing or asking about specific DBpedia topics 3.Use a helpful, conversational tone

Changes Made- Modified src/main/resources/eliza/script: Updated key: what responses to be more helpful and DBpedia-focused Updated key: why responses to acknowledge limitations instead of psychoanalyzing Added key: how responses with helpful fallback messages Improved other generic fallback responses throughout the script
