Minor Changes

• #2207 1b5f0c7 Thanks @github-actions! - close FiberHandle/FiberSet/FiberMap when it is released

  When they are closed, fibers can no longer be added to them.

• #2207 d50a652 Thanks @github-actions! - add preregisteredWords option to frequency metric key type

  You can use this to register a list of words to pre-populate the value of the
  metric.

  import { Metric } from "effect";
  
  const counts = Metric.frequency("counts", {
    preregisteredWords: ["a", "b", "c"],
  }).register();

• #2207 9a3bd47 Thanks @github-actions! - Bump TypeScript min requirement to version 5.4

• #2207 be9d025 Thanks @github-actions! - add unique identifier to Tracer.ParentSpan tag

• #2529 78b767c Thanks @fubhy! - Renamed ReadonlyArray and ReadonlyRecord modules for better discoverability.

• #2207 a18f594 Thanks @github-actions! - support variadic arguments in Effect.log

  This makes Effect.log more similar to console.log:

  Effect.log("hello", { foo: "bar" }, Cause.fail("error"));

• #2207 2f96d93 Thanks @github-actions! - Fix ConfigError _tag, with the previous implementation catching the ConfigError with Effect.catchTag would show And, Or, etc.

• #2207 5a2314b Thanks @github-actions! - replace use of unit terminology with void

  For all the data types.

  Effect.unit; // => Effect.void
  Stream.unit; // => Stream.void
  
  // etc

• #2207 271b79f Thanks @github-actions! - Either: fix getEquivalence parameter order from Either.getEquivalence(left, right) to Either.getEquivalence({ left, right })

• #2207 53d1c2a Thanks @github-actions! - use LazyArg for Effect.if branches

  Instead of:

  Effect.if(true, {
    onTrue: Effect.succeed("true"),
    onFalse: Effect.succeed("false"),
  });

  You should now write:

  Effect.if(true, {
    onTrue: () => Effect.succeed("true"),
    onFalse: () => Effect.succeed("false"),
  });

• #2207 e7e1bbe Thanks @github-actions! - Replaced custom NoInfer type with the native NoInfer type from TypeScript 5.4

    const handle = yield* _(FiberHandle.make());
  
    // run some effects
    yield* _(FiberHandle.run(handle, Effect.never));
    // this will interrupt the previous fiber
    yield* _(FiberHandle.run(handle, Effect.never));
    // this will not run, as a fiber is already running
    yield* _(FiberHandle.run(handle, Effect.never, { onlyIfMissing: true }));
  
    yield* _(Effect.sleep(1000));
  }).pipe(
    Effect.scoped, // The fiber will be interrupted when the scope is closed
  );
