refactor: Simplify pycli installation to use PATH environment variable

- Modify install_pycli.sh to add ~/.claude/scripts/ to PATH instead of creating alias
- Remove redundant alias configuration, use direct PATH registration
- Update documentation to reflect simplified installation process
- Delete README.md as requested by user
- Now users can call 'pycli' directly after installation without alias setup

Installation process:
1. Run install_pycli.sh
2. Reload shell configuration (source ~/.bashrc)
3. Use 'pycli' command directly
