A 70-line newtype lived in picloud/src/lib.rs wrapping
Arc<PostgresScriptRepository> and re-implementing every ScriptRepository
method as `self.0.method(...).await`. Hand-delegation invited silent
skew when the trait gained a method, and forced 8 call sites to know
about the wrapper.
Add a blanket
impl<T: ScriptRepository + ?Sized> ScriptRepository for Arc<T>
in manager-core::repo. The implementations forward via (**self).method(...)
so any owner of an Arc<dyn ScriptRepository> (or Arc<ConcreteImpl>) can
be passed where the trait is expected.
Migrate the 7 picloud-binary call sites:
Arc::new(PostgresScriptRepoHandle(script_repo.clone())) → script_repo.clone()
Delete the newtype + its hand-delegated impl. Leaves a 6-line comment
documenting why the boilerplate is gone.
