#### in the emit routes, I would like to add the payload in the types outputed if there is any  

I'll add payload information to the routes output. I need to extract the request body parameters from the HTTP operation and include them in the route definition.

src/emit_routes.ts
```typescript
<<<<<<< SEARCH
      // getUrl
      const pathParams = httpOp[0].parameters.parameters.filter(
        (p) => p.type === "path",
      );
      const pathParamsArgsString = pathParams
        .map((p) => `${p.name}: string`)
        .join(", ");
      const pathParamsArg = `params: {${pathParamsArgsString}}`;
      const pathParamsOutString = pathParams.reduce(
        (sum, cur) =>
          sum.replaceAll(`{${cur.name}}`, `${"$"}{params.${cur.name}}`),
        `\`${httpOp[0].path}\``,
      );

      out = out.addLine(
        `getUrl: (${pathParams.length > 0 ? pathParamsArg : ""}): string => ${pathParamsOutString},`,
        nestLevel + 2,
      );

      // payload (request body)
      const bodyParams = httpOp[0].parameters.parameters.filter(
        (p) => p.type === "body",
      );
      const hasPayload = bodyParams.length > 0;
      out = out.addLine(
        `hasPayload: ${hasPayload},`,
        nestLevel + 2,
      );
      if (hasPayload) {
        const payloadParam = bodyParams[0];
        out = out.addLine(
          `payloadName: '${payloadParam.name}',`,
          nestLevel + 2,
        );
      }
>>>>>>> REPLACE
```

This change adds payload information to each route by:

1. Filtering the HTTP operation parameters to find body parameters
2. Adding a `hasPayload` boolean field indicating if the route expects a request body
3. If there is a payload, adding a `payloadName` field with the name of the body parameter

The payload information will now be available in the generated routes object for each operation that has a request body.
