vscode integration `--fast-only` not work

### Welcome

- [x] Yes, I'm using a binary release within 2 latest [releases](https://github.com/golangci/golangci-lint/releases). Only such installations are supported.
- [x] Yes, I've searched similar [issues on GitHub](https://github.com/golangci/golangci-lint/issues) and didn't find any.
- [x] Yes, I've read the `typecheck` section of the [FAQ](https://golangci-lint.run/docs/welcome/faq/#why-do-you-have-typecheck-errors).
- [x] Yes, I've tried with the standalone [linter](https://golangci-lint.run/docs/linters/) if available (e.g., gocritic, go vet, etc.).
- [x] I agree to follow this project's [Code of Conduct](https://github.com/golangci/golangci-lint?tab=coc-ov-file)

### How did you install golangci-lint?

go install

### Description of the problem

vscode settings

```json
{
  "go.lintTool": "golangci-lint-v2",
  "go.lintFlags": [
    "--fast-only",
    "--path-mode=abs"
  ]
}
```

The output will be like
```

2025-08-19 15:05:43.701 [info]

When I remove `"--fast-only"`, the output will be like
```

```

But golangci-lint document says
`Using it in an editor without --fast-only can freeze your editor. Golangci-lint automatically discovers the .golangci.yml config for the edited file, so you don’t need to configure it in VS Code settings.`
