refactor(core): extract global resource store into standalone container

Refactor `GlobalResources` from a type-erased `Arc<Mutex<HashMap<...>>>`
alias into a `GlobalResContainer` struct with per-resource mutexes.
This prevents nested `modify_res` calls from deadlocking, allows
independent containers to coexist, and keeps `Program`'s public
resource API unchanged.
