Module async_condition 

Single-threaded, no_std + alloc port of the AsyncCondition primitive from rust-lumanoi-core (originally under the Fuchsia BSD-style license).

Upstream source: /Users/darco/Projects/rust-lumanoi/rust-lumanoi-core/src/async_condition.rs

Differences from the upstream:

• std::sync::Mutex → core::cell::RefCell (UMSH is single-threaded).
• AtomicUsize trigger counter → Cell<usize>.

Everything else (Slab<Waker>, ticket-based deregistration, forget_ticket, the counter-snapshot check in poll_wait that prevents lost wakes across trigger-then-wait races) is preserved.

Structs
