Macro memory_bootstrap_admission 

macro_rules! memory_bootstrap_admission {
    (identity = $identity:expr, prepare = $prepare:path $(,)?) => { ... };
}

Register the artifact’s composed memory admission before Canic bootstrap.

Supply a semantic ic_memory::PolicyIdentity and a synchronous callback taking &mut ic_memory::BootstrapAdmission and returning Result<(), E> where E implements Error + Send + Sync + 'static. Register once per artifact, not per database. Grant consumer ranges separately with ic_memory_range!.
