Hermes Agent v0.20.0: streaming voice with barge-in, outbound webhooks, desktop plugin SDK

Large release centred on real-time conversational voice: Hermes now speaks clause-by-clause as it generates, can be interrupted mid-sentence, and responds to on-device wake words across CLI, desktop, and messaging gateways. It also gains signed outbound webhooks for pushing lifecycle events to external HTTP endpoints, a grounded-citations research skill, and a desktop plugin SDK with sandboxed artifact previews.
