Add comprehensive logging and enable AI section creation

Features:
- IAs can now create NEW sections if they think they're needed
- Complete document content logging (before/after each modification)
- Detailed AI thinking and reasoning in logs
- Distinguish between 'MODIFIED' and 'CREATED NEW SECTION' actions
- Full round-by-round visibility in logs

This allows AI agents to be more creative and add new architectural
sections when they identify missing requirements or design gaps.

 - If section is good, respond: "Section is good, no changes needed"
