fix(cli): Resolve bin/oxfmt as like oxlint (#1326)

- `oxfmt@0.44` added `package.json` exports
  - oxc-project/oxc#20784, for #1162
- This prevents access to unspecified subpaths
- As a result, this type of error will occur
  - https://github.com/rolldown/rolldown/actions/runs/24068646976/job/70200159260?pr=9018
  - At the moment, `vite-plus` bundles `oxfmt@0.43`, so this should not be an issue
  - It was only causing a problem because rolldown repo happened to overwrite it by installing `oxfmt@0.44` separately
- However, this issue will happen for us when updating to bundle `oxfmt@0.44` in the future

We can avoid this issue by following the `oxlint` resolution approach. And now, it's ready to update `oxfmt@0.44` safely.
