apply

Apply a local mutation. Updates state synchronously; broadcasts a QuiltMessage.Delta to all current peers asynchronously (fire-and-forget within scope).

Thread-safe. Safe to call from any thread or coroutine context — the state mutation is serialised against the inbound/peers/anti-entropy collectors by an internal reentrant lock — and remains synchronous (non-suspending): it returns once state reflects the mutation, the broadcast having been handed off to a child coroutine.
