docs(templates): recommend a few relevant integrations on the Hermes-only templates

Four bank templates (hermes-gateway-bot, hermes-orchestrator, customer-support,
research-assistant) listed only `hermes`, making them look Hermes-exclusive even
though their memory pattern fits other harnesses. Add a small, curated set of the
most relevant integrations to each (keeping `hermes`):

- hermes-gateway-bot: langgraph, crewai, agno
- hermes-orchestrator: langgraph, crewai, autogen
- customer-support:   langgraph, crewai, dify
- research-assistant: obsidian, llamaindex, langgraph

Also fixes two stale icon IDs on the conversation template
(ai-sdk -> vercel-ai-sdk, chat -> vercel-chat) so its icons resolve.

`hermes` is kept on all seven templates, so the Hermes setup picker is unaffected.
