StartupOS Monorepo Final

Added proper guest mode to StartupOS! Users can now complete the founder interview, generate a blueprint, and explore the workspace without creating an account. Also fixed a bunch of authentication edge cases, improved session handling, and ran a full Playwright audit to make the app much more stable.

Thanks for the reviews, those helped really well. For some reasons my app broke during the QA Testing and I would apologize for that. (I have fixed it now hope so!). Also I have reworked the CSS(to make it less AI slop). Also this is 100% AI free. I hope you like it
