Expose CLI via bin / npx instead of requiring manual build in node_modules

Hi team, we’re using `oobee` as a NodeJS dependency and noticed the published package does not include its built output. This is from the documentation: ```bash cd node_modules/@govtechsg/oobee npm install npm run build cd ../../.. ``` From a consumer perspective, this feels a bit unusual, as: - `node_modules` is generally treated as immutable - running `npm install` inside a dependency can lead to non-deterministic installs - this pattern is hard to automate reliably in CI/CD pipelines - package managers typically expect dependencies to be usable immediately after install Currently, we rebuild Oobee during our own `postInstall` script. Would it be possible to expose Oobee’s functionality via a CLI using the `bin` field in `package.json`? For example: - Build `dist` during publish (or CI) - Include it via the `files` field - Expose a CLI via `bin` for usage through `npx` (this will greatly help the usage of CLI programatically) - usable via `npx oobee …` or `./node_modules/.bin/oobee` This would: - remove the need to manually build inside `node_modules` - align with common npm package conventions - make the package easier to integrate in CI and other projects
