/** Deployment-identity headers (cloud definition, interaction model): every
 * key-authenticated Vendo Cloud request carries `x-vendo-deployment-host`,
 * `x-vendo-deployment-name`, and `x-vendo-deployment-version`; the console's
 * shared auth middleware upserts the deployment inventory and meters usage
 * from these on real service calls — there is no heartbeat. Shared by the
 * CLI cloud client and the runtime Cloud adapters (connections, sandbox), so
 * this module carries NO static Node import: builtins load through the
 * runtime accessor (server.ts precedent) and every lookup fails soft to
 * "unknown" on edge/Worker targets — identity headers must never take a
 * request down. The console truncates and fails open on its side
 * (parseDeploymentHeaders), so sending is always safe. */
