feat: lite version (frontend only)

[tmc]

I really enjoyed this project most when it could simply be a frontend for ollama. Please make it an option to reduce complexity and not require a backend process.

npm i; npm run dev -> working UI was wonderfully easy, and this has been lost.

I didn't get to use it back then, basically are you saying that you just connected the front end to some external API and then used it as a thin-client. Cuz if so that would actually be pretty sweet and I'd second that kind of capability

Not on the short term roadmap but PR welcome!

To clarify, our goal is to enable a frontend-only build within our existing codebase, without the need to create a separate project and remove all backend code permanently. An ideal solution would be a build-time flag for the frontend that disables backend-dependent functionality.

Additionally, this flag should save all preferences and settings to LocalStorage and allow Ollama/OpenAI API calls to be sent directly, bypassing the need for backend proxying. This will allow for a more streamlined and efficient frontend-only build based off the same codebase.
