refactor: move examples to __examples directory and update build targets

- Move all example files from examples/ to __examples/ directory
- Replace Makefile benchmark target with run-example target for running examples
- Update README.md to reflect new example directory path and make command
- Update .PHONY targets in Makefile to include run-example

This change follows Go project conventions by using __examples prefix
to clearly distinguish example code from main library code.
