// Factory mirroring openclaw's createSignalPluginBase pattern. Both
// src/setup-entry.ts (setup-only entry path) and src/channel.ts (full-runtime
// path) consume this so plugin.config / plugin.setup / plugin.setupWizard are
// identical across both surfaces. openclaw 2026.4.21+ routes `channels list`
// and `onboard` through the setup-only entry expecting `plugin.config.{listAccountIds,
// defaultAccountId, resolveAccount, isConfigured, isEnabled, describeAccount}` —
// without these the runtime crashes with TypeError on undefined.
