Crate umsh_sync 

Single-threaded async synchronization primitives for UMSH.

• AsyncCondition — a wake-all condition variable with slab-backed ticketed deregistration.
• AsyncRefCell — an async-aware RefCell whose borrow() / borrow_mut() futures wait instead of panicking when the cell is in use.

Everything here is no_std + alloc, single-threaded, and executor- agnostic: it works under tokio (with a LocalSet), embassy, or any custom async runtime that polls futures to completion.
