cmd/simplexcalc/ now holds only main.go: it passes the version the linker sets to cli.Main and exits with the status that returns. root.go and run.go move to internal/cli with their comments, changed only to take the version as a parameter. Main reads the process's arguments and output; execute takes them as parameters so the new tests can check the version line and the non-zero status of an unknown command. Commands, flags, output, log lines and exit status are unchanged, and the -X main.version flag in the Dockerfile still applies. Model: opus-5-5
