refactor: move initRunCmd to dedicated commands_run.go file

Create commands_run.go following the same modular pattern as other
command files. Move initRunCmd logic to InitRunCmd function with
consistent naming and complete functionality preservation.

Update cli.go to use InitRunCmd() instead of initRunCmd() and clean
up commands.go by removing the old function and unused imports.

This completes the modular refactoring pattern where each command type
has its own dedicated file with focused responsibility.
