Load persona from file in repo #1167
Description
Describe the need of your request
Every project is slightly different and we want to reflect this in the persona - it defines project-level rules and guidance.
Current problem: Personas and prompts are global. We have to import all personas for all projects and make sure to select the correct persona before using ProxyAI.
Also, it's easy for devs to get out of sync, as we cannot commit the persona to the repo and people do not know if their persona is still up-to-date
Proposed solution
Add support for a .proxyai config folder that can be git controlled.
All .proxyai/persona/*.json files are loaded on app start and available as read-only Personas for the current project (they cannot be edited or deleted in the plugin settings, as they are always loaded from the file)
Additional context
The goal is to add personas to a repo, and every developer using that repo has the "shared persona" available, and those personas do not spill over to other projects.
