HttpLayerRouter is mixing error schemas between different APIs

[matheuspuel]

What version of Effect is running?

3.21.2

What steps can reproduce the bug?

This is a minimal reproduction of the issue:

import { HttpApi, HttpApiBuilder, HttpApiEndpoint, HttpApiGroup, HttpLayerRouter } from "@effect/platform"
import { NodeHttpServer } from "@effect/platform-node"
import { Effect, Layer, Schema } from "effect"

const Api1 = HttpApi.make("Api1").add(
  HttpApiGroup.make("group1").add(
    HttpApiEndpoint.post("endpoint1")`/1`.addError(Schema.transformLiteral("BAD", "x"))
  )
)
const Handlers1 = HttpApiBuilder.group(Api1, "group1", (_) => _.handle("endpoint1", () => Effect.void))
const Routes1 = HttpLayerRouter.addHttpApi(Api1).pipe(Layer.provide(Layer.mergeAll(Handlers1)))

const Api2 = HttpApi.make("Api2").add(
  HttpApiGroup.make("group2").add(
    HttpApiEndpoint.get("endpoint2")`/2`.addError(Schema.transformLiteral("GOOD", "x"))
  )
)
const Handlers2 = HttpApiBuilder.group(Api2, "group2", (_) => _.handle("endpoint2", () => Effect.fail("x" as const)))
const Routes2 = HttpLayerRouter.addHttpApi(Api2).pipe(Layer.provide(Layer.mergeAll(Handlers2)))

const AllRoutes = Layer.mergeAll(Routes1, Routes2)
const { handler } = HttpLayerRouter.toWebHandler(AllRoutes.pipe(Layer.provide(NodeHttpServer.layerContext)))

const request = new Request("http://localhost:3000/2")
const response = await handler(request)
const text = await response.text()
console.log(text)

What is the expected behavior?

Should log "GOOD", because of the transformation defined in the error schema for the endpoint 2.

What do you see instead?

It is logging "BAD" instead, incorrectly using the error schema from the endpoint 1.

Additional information

It works correctly if remove Layer.mergeAll from Layer.provide(Layer.mergeAll(Handlers2)). It is unnecessary in this minimal example, but is required for registering multiple endpoints in the same API.
