// Operator convenience (Guild C-2): print the commands-sync key that this
// guild process actually has in its environment, so it can be copied into
// the OpenClaw plugin's FABRIC_COMMANDS_SYNC_KEY.
//
// Usage (inside the deployed container — authoritative, reflects compose):
//   docker exec fabric-backend-guild node dist/cli/print-commands-sync-key.js
//   docker exec fabric-backend-guild node dist/cli/print-commands-sync-key.js --export
//
// Default: prints the raw value only (so KEY=$(... ) works).
// --export: prints `FABRIC_COMMANDS_SYNC_KEY=<value>` for pasting.
// Exit 1 (no stdout) when unset — guild is then in the weaker
// "any authenticated user" fallback for PUT /commands.
