Add RemoteBash tool to response agent

add a new tool to the response agent: RemoteBash (that uses our very own remote-bash API). it should be used if the user references another github repository and the agent wants to send bash commands against it

let's actually just npx remote-bash instead! that will be easier and more powerful.

also, can u add a regular Bash tool that behaves like the RemoteBash (uses just-bash etc) just that for the local mounted directory?

there's a slight thing we need to change: Bash in ask mode should be different than ask in build mode. in ask mode, it should behave like remote-bash does: use just-bash in readonly (it does that, right?) so ask doesn't write.
