Projects: re-usable system prompt, model settings and context

[fmaclen]

This issue describes a new high-level entity called "Projects". Loosely inspired by Claude's: https://www.anthropic.com/news/projects

• Projects could include:
  • System prompt
  • One or more additional Knowledge for context
  • Advanced model options (i.e temperature, seed, etc)
• User could start a New session and choose a Project which would apply all of the parameters/context.

Additional thoughts:

• If user chooses a Project when starting a New session, should the settings be updatable at that point?
• Should the settings be updatable in the middle of an existing Session?
• If these options need to be editable we might want to use use the initial Project as a "base template" that we apply and store together with a Session.
• One thing to consider if we treat Projects as templates and we "create copies" for every New session is that it could have a noticeable negative impact in performance/storage capacity.

For reference, here's a screenshot from OpenWebUI for the Advanced controls when creating a new chat:

Here's a draft of a potential UI implementation of some the requirements above:
