PR Title

Add conversational natural-language search to advanced Stellar dashboard search

Summary

This PR adds a conversational query interface to the advanced search dashboard and fixes a JSX parse issue in AdvancedSearch.tsx.

What changed

• Added ConversationalSearch.tsx
  • New conversational search component with:
    • natural language input
    • intent classification
    • follow-up suggestions
    • parsed query preview
    • recent conversational query history
• Integrated ConversationalSearch into AdvancedSearch.tsx
  • wired handleConversationalQuery() into dashboard search flow
  • updates filters and executes search from parsed natural language input
  • displays detected intent summary
• Fixed syntax error in AdvancedSearch.tsx
  • removed stray duplicate JSX closing )} that caused parse failure
• Cleaned up state usage in ConversationalSearch.tsx
  • ensured parsed intent state is rendered and no longer unused

Files changed

• AdvancedSearch.tsx
• ConversationalSearch.tsx

Testing

• Verified both updated files report no parse/lint errors
• Manual validation of conversational query component render flow
• Confirmed search execution path remains intact after fix

Notes

• This PR is focused on UI integration and structured query conversion.
• Future follow-up can add export/results export support from conversation results or deeper follow-up question chaining.
