Add "Pair AI" feature to automatically generate AI note copies

[rajin-khan]

One-liner

Add a "Pair AI" feature that automatically creates AI-enhanced versions of notes after a period of inactivity.

Proposed Behavior

When a user writes a note and the editor REMAINS CLOSED/user is offline for more than 30 seconds, the system should automatically:

1. Detect the inactivity period
2. Generate an AI-enhanced/extended version of the note
3. Save it as a new file with the naming convention: [original-name] - (Puffed).md

Example

• Original note: meeting-notes.md
• AI-generated copy: meeting-notes - (Puffed).md

Implementation Considerations

• Monitor editor activity to detect 30-second idle periods
• Integrate AI service for note enhancement/extension
• Handle file naming conflicts if a "(Puffed)" version already exists
• Consider adding user preferences to enable/disable this feature or adjust the timeout duration
• Determine what "extended" means (e.g., expanded explanations, added context, reformatted content)

Questions

• Should this feature be opt-in or opt-out?
• What level of AI enhancement is desired? (expansion, summarization, formatting, etc.)
• Should users be notified when a Puffed version is created?
