Issue: Improve `bootstrap.js` to support both Yarn and NPM with clearer errors

[itspavant]

Feature request for Cloudinary React Native SDK

Improve scripts/bootstrap.js to support both Yarn and NPM with clearer error handling.

Explain your use case

When contributing to this repository, new developers typically start with npm install.
However, the current scripts/bootstrap.js assumes Yarn is installed.
If Yarn is missing, the script fails without guidance, making onboarding harder for contributors who default to npm.

Describe the problem you’re trying to solve

Right now:

• The script hardcodes Yarn and fails if it’s not installed.
• There is no fallback to npm run bootstrap.
• If bootstrap is not defined in package.json, the script exits with no explanation.

This creates friction for new contributors and may result in unnecessary issues being opened.

Do you have a proposed solution?

Yes.

• Detect if Yarn is available; if not, fall back to npm run bootstrap.
• Allow contributors to explicitly prefer npm (e.g. with a flag like --use-npm).
• Validate that a bootstrap script exists in package.json before trying to run it.
• Print clear, contributor-friendly error messages when something fails.

This change would not alter the default behavior for Yarn users, but it would improve reliability, reduce confusion, and make onboarding easier for developers using npm.

Hiiii @jlooper

Thank you for clarifying! I only asked for assignment earlier because I thought it was required for the issue/PR to count towards Hacktoberfest 2025 points and to be eligible for Cloudinary swag. Nothing else beyond that.

I’ve now created PR #51 — kindly review it when you get a chance, and please let me know if any modifications are needed.

Thanks again!
