/**
 * Stdout discipline for machine-readable (`--json`) command modes.
 *
 * Surfaced OpenLore subcommands are spawned by OpenSpec as child processes; a
 * consumer parsing stdout must never get log noise mixed in. The logger routes
 * info/success/discovery/warning to stdout via console.log, so in `--json` mode any
 * such line would corrupt the JSON. These helpers redirect console.log/info/warn to
 * stderr for the duration of the work, leaving process.stdout.write (used to emit
 * the JSON) clean. The MCP server applies the same discipline; logger.error already
 * uses stderr.
