Saving skills to account settings in AI Agent

🔍 Problem Statement
As an AI Agent user running recurring reports, I must re-explain rules and business processes in every new conversation, wasting time and causing inconsistent output.

💡 User Story
As an AI Agent user, I want to save reusable rules/processes to a shared project, so that new conversations reuse them automatically without re-explaining.
As a teammate, I want access to shared project rules, so that I can run the same reports consistently without rebuilding context.

🎯 Definition of Done (DoD)
✔ Given a saved project with stored rules, when a new conversation starts within that project, then the AI Agent applies those rules without re-entry.
✔ Given a project with multiple members, when a teammate opens the project, then they see and can use the same stored rules.
