Move inactive projects out of active workspace:
- bauntown (community website)
- maerchenzauber (AI story generation)
- memoro (voice memo app)
- news (news aggregation)
- nutriphi (nutrition tracking)
- reader (reading app)
- uload (URL shortener)
- wisekeep (AI wisdom extraction)

Update CLAUDE.md documentation:
- Add presi to active projects
- Document archived projects section
