Patch Changes

• #2145 b1163b2 Thanks @tim-smart! - add RequestResolver.aroundRequests api

  This can be used to run side effects that introspect the requests being
  executed.

  Example:

  import { Effect, Request, RequestResolver } from "effect";
  
  interface GetUserById extends Request.Request<unknown> {
    readonly id: number;
  }
  
  declare const resolver: RequestResolver.RequestResolver<GetUserById>;
  
  RequestResolver.aroundRequests(
    resolver,
    (requests) => Effect.log(`got ${requests.length} requests`),
    (requests, _) => Effect.log(`finised running ${requests.length} requests`),
  );

• #2148 b46b869 Thanks @riordanpawley! - Flipped scheduleForked types to match new <A, E, R> signature

• #2139 de1b226 Thanks @mikearnaldi! - Introduce FiberId.Single, make FiberId.None behave like FiberId.Runtime, relax FiberRefs to use Single instead of Runtime.

  This change is a precursor to enable easier APIs to modify the Runtime when patching FiberRefs.

• #2137 a663390 Thanks @mikearnaldi! - Expose Random Tag and functions to use a specific random service implementation

• #2143 ff88f80 Thanks @mikearnaldi! - Fix Cause.pretty when toString is invalid

  import { Cause } from "effect";
  
  console.log(Cause.pretty(Cause.fail([{ toString: "" }])));

  The code above used to throw now it prints:

  Error: [{"toString":""}]

• #2080 11be07b Thanks @KhraksMamtsov! - Add functional analogue of satisfies operator.
  This is a convenient operator to use in the pipe chain to localize type errors closer to their source.

  import { satisfies } from "effect/Function";
  
  const test1 = satisfies<number>()(5 as const);
  // ^? const test: 5
  
  // @ts-expect-error
  const test2 = satisfies<string>()(5);
  // ^? Argument of type 'number' is not assignable to parameter of type 'string'

• #2147 c568645 Thanks @tim-smart! - generate a random span id for the built-in tracer

  This ensures the same span id isn't used between application runs.

• #2144 88835e5 Thanks @mikearnaldi! - Fix withRandom and withClock types

• #2138 b415577 Thanks @mikearnaldi! - Fix internals of TestAnnotationsMap making it respect equality

• #2149 ff8046f Thanks @tim-smart! - add Runtime.updateFiberRefs/setFiberRef/deleteFiberRef

  This change allows you to update fiber ref values inside a Runtime object.

  Example:

  import { Effect, FiberRef, Runtime } from "effect";
  
  const ref = FiberRef.unsafeMake(0);
  
  const updatedRuntime = Runtime.defaultRuntime.pipe(
    Runtime.setFiberRef(ref, 1),
  );
  
  // returns 1
  const result = Runtime.runSync(updatedRuntime)(FiberRef.get(ref));
