Annotations fail to properly decode pointers

The following code produces an error:

import { registerSchema } from "@hyperjump/json-schema/draft-2020-12";
import { annotate } from "@hyperjump/json-schema/annotations/experimental";

const schemaId = "https://fabc10a6-e699-415c-b5e2-25702695a939.example.hudlow.org";

const schema = {
  $schema: "https://json-schema.org/draft/2020-12/schema",
  $id: schemaId,
  properties: {
    paths: {
      properties: {
        "/pets/{id}": {
          title: "path",
          properties: {
            get: {}
          }
        }
      }
    }
  }
};

registerSchema(schema);

const instance = await annotate(schemaId, {
  paths: {
    "/pets/{id}": {
      get: {}
    }
  }
});

Node.js v18.17.1

The reason is that the JSON pointers for the instance location of an annotation are not properly URI-decoded. Consider the the above schema will produce this annotations value:

{
  "/paths/~1pets~1%7Bid%7D": { "https://json-schema.org/keyword/title": [ "path" ] }
}

But this is wrong — because this annotations object is not keyed by a relative pointer URI, but rather by the fragment value from a relative pointer URI, it should be:

{
  "/paths/~1pets~1{id}": { "https://json-schema.org/keyword/title": [ "path" ] }
}

This mismatched logic produces the error, but the annotations are actually themselves wrong.
