Fix ACP extension root dir (#42131)

Richard Feldman created 3 weeks ago

Agents running in extensions need to have a root directory of the
extension's dir for installation and authentication, but *not* for the
conversation itself - otherwise the agent is running things like
terminal commands in the wrong dir.

Release Notes:

- Fixed Agent Server extensions having the current working directory of
the extension rather than the project
