Async

Modules: async/future, async/runtime

Seen's async stdlib surface provides the basic future/task types used by compiler and application code that lowers async, await, and coroutine-style work.

Type	Module	Purpose
`Future`	`async/future`	Future contract and polling state
`Context`	`async/future`	Polling context passed to futures
`Waker`	`async/future`	Wake handle for suspended work
`ThenTask`	`async/future`	Future continuation helper
`MapTask`	`async/future`	Future mapping helper
`CoroutineTask`	`async/runtime`	Runtime task wrapper
`AsyncRuntime`	`async/runtime`	Simple async runtime coordinator
`AsyncScope`	`async/runtime`	Scope for grouped async work
