Dedicated Workout Library and Community Sharing

[hdkiller]

💡 Summary

Implement a dedicated workout library within Coach Watts, allowing users to build a "pool" of workouts that can be accessed by the AI Coach and shared with other users/groups.

🤷 Motivation / Use Case

Currently, the coach primarily interacts with the Intervals.icu library/calendar. A native library would allow for a larger, shared workout pool (e.g., with friends or training partners) that the coach can access directly without requiring the workouts to be scheduled on a calendar first.

📋 Detailed Requirements

• Workout Pool: A centralized storage for custom workout definitions.
• Sharing: Ability to share workouts with friends or groups.
• Direct Access: AI Coach integration to suggest workouts directly from this library.
• Upload/Import: Support for uploading workout files or importing from common formats.

✅ Acceptance Criteria

• Users can save workouts to a personal library.
• Users can view and use workouts shared by friends.
• The AI Coach can reference the library when providing training recommendations.
