Dev server breaks as soon as I generate a new controller

Hey there!

I was going to give bud a shot and unfortunately I got stuck right after generating a new controller, getting this error:

```
| genfs: open "bud/cmd/app/main.go". genfs: open "bud/internal/web/web.go". genfs: open
"bud/internal/web/controller/controller.go". framework/controller: unable to load. controller: unable to load:
"/snap/go/current/src/context" can't be outside the module directory "/snap/go/10257/src"
```

To reproduce:

```sh
curl -sf https://raw.githubusercontent.com/livebud/bud/main/install.sh | sh
bud create hello
cd hello

# in one tab
bud run

# in another tab
bud new controller home:/ index
```

As soon as the browser attempts to refresh the page that error occurs, the browser hangs and the request never completes. If I stop the server and try to spin it up again I get the same error and it never comes up.

Some information about my environment:
- Ubuntu 22.04.2
- `go version go1.20.6 linux/amd64` installed with `snap install`
- `bud: 0.2.8`
- `svelte: 3.47.0`
- `react: 18.0.0`

```

Reproduce with `bud create hello`, `bud run`, and `bud new controller home:/ index` on the reported Ubuntu/Snap Go setup. Start with the generated `bud/cmd/app/main.go`, `bud/internal/web/web.go`, and `bud/internal/web/controller/controller.go` paths and the `framework/controller` load failure. Done means the browser refresh completes and the dev server can restart without the module-directory error.
