L1: declares the main package so the file builds to a binary.
L3-L11: imports standard IO/OS plus cobra for CLI wiring and zap for logging, pulling CLI commands from internal/cli.
L13-L17: version metadata variables (version, commit, date) defaulted for local builds and typically set at link time.
L19-L33: main() builds a console logger, aborts on failure, defers sync, registers all subcommands via initCommands, and executes the Cobra root command; errors are printed to stderr and exit non-zero.
L35-L48: rootCmd defines the Cobra root with usage text, a multi-line description of the platform management focus, and a version string that includes build metadata.
L50-L57: initCommands attaches the cluster, registry, server, access, bootstrap, setup, status, sentinel, and pipeline subcommands (nine total) provided by internal/cli packages using the shared logger.
L60-L82: newConsoleLogger creates a zap production config tuned for human console output (console encoding, warn level, ISO timestamps, colored levels, no caller/stack info) and directs output to stdout/stderr.
