sdks/python: mirror Elydora-Python-SDK 2.0.2

Rebuilt from the standalone 54e65eb tree (durable transactions, Kiro IDE
adapter, hook retry with a bounded chain lock, version 2.0.2) with the
Open-Source API trims re-applied: no token rotation, token issuance, or
agent integration updates, and the mirror's registration contract and
OpenCode plugin tests kept.
