Patch Changes

• #2211 20e63fb Thanks @tim-smart! - add ManagedRuntime module, to make incremental adoption easier

  You can use a ManagedRuntime to run Effect's that can use the
  dependencies from the given Layer. For example:

  import { Console, Effect, Layer, ManagedRuntime } from "effect";
  
  class Notifications extends Effect.Tag("Notifications")<
    Notifications,
    { readonly notify: (message: string) => Effect.Effect<void> }
  >() {
    static Live = Layer.succeed(this, {
      notify: (message) => Console.log(message),
    });
  }
  
  async function main() {
    const runtime = ManagedRuntime.make(Notifications.Live);
    await runtime.runPromise(Notifications.notify("Hello, world!"));
    await runtime.dispose();
  }
  
  main();

• #2211 20e63fb Thanks @tim-smart! - add Layer.toRuntimeWithMemoMap api

  Similar to Layer.toRuntime, but allows you to share a Layer.MemoMap between
  layer builds.

  By sharing the MemoMap, layers are shared between each build - ensuring layers
  are only built once between multiple calls to Layer.toRuntimeWithMemoMap.
