silent failure when setting an empty string as the path in e.g. @Get() and @Post() decorators

[Thesephi]

Version: latest (0.12.2 atm)
Reproduction:

@Controller()
export class MyController {
  @Post("")
  @ControllerMethodArgs("body")
  listen(
    body: any
  ) {
    console.log("received", body);
    return "to be implemented";
  }
}

Expectation: the snippet above results in the index route (/) being handled
Actual:

* Connected to localhost (127.0.0.1) port 1993
> POST / HTTP/1.1
> Host: localhost:1993
> User-Agent: curl/8.5.0
> Accept: */*
> Content-Type: application/json
> Content-Length: 13
>
< HTTP/1.1 404 Not Found
< content-length: 0
< date: Wed, 11 Dec 2024 01:52:13 GMT
<
* Connection #0 to host localhost left intact

Notes: even this seems to be an unconventional (undocumented) usage (ie setting an empty string "" as the path, instead of a slash /), it's better to choose between:

1. throwing an error or visible warning
2. just defaulting empty string to / (and treating it as the index route by default)

Either approach above is better than silently failing / not handling the route like currently.
