- Add new 'install-to DIR' subcommand that copies the running binary to a specified directory - Uses atomic operations: copy to temp file, then rename for atomicity - Preserves executable permissions (755) from original binary - Handles errors gracefully with proper exit codes and cleanup - Validates destination directory exists and is actually a directory - Integrated with existing help system and command structure Implementation details: - New file: internal/cli/commands_install_to.go - core functionality - New file: internal/cli/commands_install_to_test.go - comprehensive test suite - Modified: internal/cli/main.go - CLI integration and command parsing Testing: - 7 test functions covering unit and integration testing - Tests atomic operations, error handling, permission preservation - Tests CLI interface, help system, and edge cases - All tests passing This feature enables easy binary deployment and self-updating workflows while maintaining compatibility with upstream migrate project structure.
