defineRouteMeta needs to take a type parameter for examples value

Describe the feature

defineRouteMeta({
  openAPI: {
    tags: ["test"],
    description: "Test route description",
    requestBody: {
      required: true,
      content: {
        "application/json": {
          description: "Payload",
          summary: "Payload",
          schema: SomeInputSchemaJson,
          examples: {
            my_correct_example {
              summary: "an awesome example",
              value: {
                 yayValidField: 'nice'
              },
            },
            my_incorrect_example {
              summary: "oops",
              value: {
                 failTrain: 'lmao'
              },
            },
          },
        },
      },
    },
    responses: {
      "200": {
        summary: "Success",
        description: "Success",
        content: {
          "application/json": {
            encoding: {},
            schema: SomeOutputSchemaJson,
          },
        },
      },
    },
  },
});

Given the above route meta, we should be able to ensure that we get type safety when inserting incorrect example data structure :

defineRouteMeta<SomeInput>({
  openAPI: {
    tags: ["test"],
    description: "Test route description",
    requestBody: {
      required: true,
      content: {
        "application/json": {
          description: "Payload",
          summary: "Payload",
          schema: SomeInputSchemaJson,
          examples: {
            my_correct_example {
              summary: "an awesome example",
              value: {
                 yayValidField: 'nice'
              },
            },
            my_incorrect_example {
              summary: "oops",
              value: {
                 failTrain: 'lmao' 👈👈👈👈👈👈👈👈 should now show error
              },
            },
          },
        },
      },
    },
    responses: {
      "200": {
        summary: "Success",
        description: "Success",
        content: {
          "application/json": {
            encoding: {},
            schema: SomeOutputSchemaJson,
          },
        },
      },
    },
  },
});

Additional information

• Would you be willing to help implement this feature?

The issue names defineRouteMeta but no source files or tests. Start by locating its TypeScript definition and the OpenAPI requestBody content types, then inspect how examples values are typed. Done means a generic such as SomeInput causes incorrect example fields to be rejected while valid values remain accepted.
