cu29-helpers

This crate is intentionally retired.

It exists as a compatibility stub so downstream users who still depend on cu29-helpers get a compile-time migration message that points them at the new generated app builder API:

let mut app = MyApp::builder()
    .with_log_path(log_path, slab_size)?
    .build()?;

If the app needs a custom clock, logger, config override, or resource factory, set those through the builder before calling .build().
