Enhance Directory Client Library for NIP-XX Protocol

- Introduced a TypeScript client library for the Distributed Directory Consensus Protocol (NIP-XX), providing a high-level API for managing directory events, identity resolution, and trust calculations.
- Implemented core functionalities including event parsing, trust score aggregation, and replication filtering, mirroring the Go implementation.
- Added comprehensive documentation and development guides for ease of use and integration.
- Updated the `.gitignore` to include additional dependencies and build artifacts for the TypeScript client.
- Enhanced validation mechanisms for group tag names and trust levels, ensuring robust input handling and security.
- Created a new `bun.lock` file to manage package dependencies effectively.
