feat(agent): add Hermes Agent (Nous Research) (#2023)

Implements Hermes Agent on Sprite cloud. Hermes is a persistent AI
agent by Nous Research with multi-platform messaging (Telegram,
Discord, Slack, CLI), memory across sessions, tool use, and native
OpenRouter support.

- Add hermes agent entry to manifest.json with env config
- Add matrix entries for all 7 clouds (sprite implemented, rest missing)
- Create sh/sprite/hermes.sh thin bash shim

Closes #1952
