Multi-file analysis

[DetachHead]

currently many rules are limited by the fact that ruff can't do multifile analysis (eg. #6932)

raising a central tracking issue for this as suggested in #6932 (comment)

is there any defined roadmap or plan for this? I can imagine it's a complicated problem to solve, especially without significant performance regressions. Would it be opt in?

We are designing this right now. The roadmap is still being determined. As always, performance will be very important to us :)
