Hermes Agent expands plugin system

Hot take: this is the kind of infrastructure update that quietly matters more than a flashy feature launch because it turns Hermes into a routing and orchestration layer, not just another agent wrapper.

• –Custom inference providers can be dropped in as plugins, which lowers integration friction for teams with proprietary or self-hosted backends.
• –The plugin model also covers memory and context engines, so Hermes is moving toward a composable agent runtime instead of a fixed product surface.
• –Built-in providers already ship as plugins, which suggests the architecture is meant to scale across many vendors and fallback paths.
• –For builders, this is a strong signal that Hermes is optimizing for extensibility and multi-provider workflows, not lock-in.
