Integrate ACP for agents CLI

[soliman-hub]

Hi,
As a dev ACP from zed and jetBrains is quite something since it add CLI directly inside a chat windows.

This plugin https://github.com/RAIT-09/obsidian-agent-client uses Agent Client Protocol (ACP) and hence use Claude Code. This helps us to avoid API keys and use Claude subscription. Could similar approach be adopted here?
