Implement a new example demonstrating how MCP servers can dynamically update available tools
at runtime and how clients can detect these changes.
- Add Server implementation that starts with weather forecast tools and dynamically adds math operation tools
- Add Client implementation that detects tool changes via MCP notifications
- Complete client/server architecture with proper tool registration and discovery
- Add detailed README explaining the dynamic tool update process and implementation
