mizu: Single-Producer Single-Consumer Channels

Provides a single-producer single-consumer channel with bounded capacity, optional timeouts on receives, and sentinel return values for full, timeout, and closed states. The ring buffer is implemented in C: sends and receives are constant-time operations, values are delivered in first-in first-out order, and a closed channel drains its buffered values before reporting the closed state. The transport is in-process: both ends of a channel live in the calling R process, which suits the channel to prototyping producer and consumer designs and to testing channel-based logic.
