test(agents): keep ide-agent tests off the user's profile and git settings (#2168)

Four ide-agent tests failed on a Windows machine with a normal setup: skill discovery walked up from a temp project into the real profile's skills, and a fixture repo inherited the global core.autocrlf. The fixtures now bound the walk at the project and turn autocrlf off.
