chore: clean up repository - remove node_modules from version control

- Remove accidentally committed node_modules directory from git tracking
- Update .gitignore with comprehensive Node.js best practices
- Add proper Jest configuration for TypeScript testing
- Add comprehensive test suite for all 23 MCP tools
- Remove obsolete src/index.ts file
- Ensure tests directory is properly tracked in version control

This commit follows Node.js best practices by excluding generated dependencies
from version control while preserving important project files and tests.
