People seemed receptive [on #toolchain](https://discord.com/channels/655572317891461132/655578254970716160/1379196447827689553), so proceeding. For the two name conflicts, I've set it up so that there's a "foo.carbon" and "foo_with_prelude.carbon", to indicate that the no-prelude approach is preferred (with a shorter name). Note min_prelude will require a little more work/thought, I want to avoid adding `--custom-core` etc.
