/**
 * Dynamic workflow run entrypoint
 *
 * Runs inside an ephemeral run execution container or process.
 * Dynamically discovers and loads workflow definitions from the user's project
 * using the Veryfront API backend.
 *
 * This is the recommended entrypoint for multi-tenant deployments where
 * user code is stored in the Veryfront API and not bundled into the container.
 *
 * Environment variables:
 * - WORKFLOW_RUN_ID: The workflow run to execute
 * - RUN_EXECUTION_ID: Immutable execution identity assigned by the run manager
 * - TENANT_PROJECT_SLUG: Tenant's project slug
 * - TENANT_TOKEN: Tenant's API token
 * - TENANT_PROJECT_ID: Tenant's project ID
 * - TENANT_PRODUCTION_MODE: Whether running in production mode
 * - TENANT_RELEASE_ID: Current release ID (optional)
 * - REDIS_URL: Redis connection URL
 * - VERYFRONT_API_URL: Veryfront API URL (default: https://api.veryfront.com)
 *
 * Exit codes:
 * - 0: Workflow completed successfully
 * - 1: Workflow failed
 * - 2: Configuration error
 * - 3: Workflow not found
