telos-receipt native verifier attribution

The _native_vendor/hermes_v2.py and _native_vendor/verify_native_v2.py
modules are adapted from native verification work for the
TELOS-Labs-AI/hermes-agent fork (https://github.com/TELOS-Labs-AI/hermes-agent),
whose upstream Hermes project is maintained by Nous Research.
The native vendored modules carry the upstream MIT notice below.
Changes in this distribution remove host-specific path discovery and dependency
loaders, use installed package imports, and pin the edited verifier sources.
