Use advanced MCP features?

[shykes]

MCP supports features other than tool calls. Should we use them? For example:

• Resources (files and directories for the agent to use)
• Prompts (mapped to slash commands in Zed and VS Code)
• Roots (exchange information about current workspace)
• Sampling ("callbacks" to prompt the agent's llm)

#211 tried out roots support, but it doesn't seem to have any real UX advantage right now. it could ostensibly be used to improve security, though.
