Based on commit 1dbe4db - Split into two crates, lib and cli - upgrade stwo, marked one stwo test `should_panic` @ShuangWu121 - various clippy and fmt fixes linked to the rust version update - bring all rust versions to 2025-05-14. CI still installs other versions for openvm which uses them internally. The stable rust version we test on is bumped to 1.85 - remove `examples` and related tests, which test the powdr crate on the previous version of powdr (since it uses another nightly). Happy to discuss this if it's important @leonardoalt
