Initialize TypeScript library for Telegram Web App wallet integration

- Added configuration files: .eslintrc.js, .gitignore, .npmrc, .prettierrc, and multiple tsconfig files for different module systems.
- Created package.json with dependencies and scripts for building, testing, and publishing.
- Implemented core functionality in src/ directory, including wallet management, encryption, and storage handling.
- Added README.md for documentation on installation, usage, and development setup.
- Introduced initial types and constants for better type safety and code organization.
