fix: Update private key field in chat integration documentation

- Change the private key field name from "prvkey" to "prvkey_hex" in the CHAT_INTEGRATION.md file for clarity and consistency with expected data formats.

feat: Add Fuzzy Search Component and Composable

- Introduce a new FuzzySearch component for Vue 3, leveraging Fuse.js for intelligent search capabilities.
- Implement a useFuzzySearch composable for flexible search functionality, allowing configuration of search options.
- Create demo and README files to showcase usage and features of the fuzzy search implementation.
- Update package.json and package-lock.json to include @vueuse/integrations version 13.6.0 for enhanced performance.
