sdks/node: mirror Elydora-Node-SDK 2.0.1

Rebuilt from the standalone 2101cb7 tree (durable transactions, Kiro IDE
adapter, hook retry with a bounded chain lock, version 2.0.1) with the
Open-Source API trims re-applied: no webhooks, members, admin events,
deep health, token rotation, or agent integration updates.
