Hermes Agent: Disable Toolsets Globally

`agent.disabled_toolsets` Hermes Agent picks its tools per platform: the CLI, Telegram, Discord and the rest each keep their own list of toolsets, set in `hermes tools`. this key is one list above all of them. a toolset named here is removed everywhere at once, on the CLI and on every gateway platform. it is applied after the per-platform lists. `web` takes web_search and web_extract out of every session. `memory` removes the memory tools and also drops the memory guidance from the prompt.
