Adds sage-client-direct, a client for plain blocking code with no effect library dependency. Each command blocks the calling thread and returns its result, failures are thrown, and interrupting the thread cancels the wait. It is meant for virtual threads, for example in frameworks such as Eezo that serve each request on one.

SageClient.use(SageConfig.fromUri(sys.env("REDIS_URL"))) { client =>
  client.set("greeting", "hello")
  val greeting = client.get[String]("greeting") // Some("hello")
}

• sage-compat-direct binds kyo.compat with plain JDK code and passes the conformance suite. Long flatMap chains continue on a fresh virtual thread to stay stack-safe, and lock bodies always run on the caller's thread so they keep its thread-local context.
• Streaming helpers return Iterator. Subscriptions return a closeable blocking iterator, and onMessage, onPatternMessage, and onShardMessage deliver messages to a callback on a background virtual thread.
• Adds the direct cells to CI, the examples, the benchmarks, and the docs.
