Users can now delete the ai-therapy-kit repo after setup. Key changes:
- Setup copies ALL components to .therapy/library/ for local customization
- Customization reads from library/ instead of source_repo
- Updates fetch directly from GitHub via WebFetch
- Added natural language triggers for customization requests
- Added discoverability hints (first-session closing, help response)
- Removed source_repo from version.json (only source_url remains)
- Deleted obsolete setup.sh and setup.ps1 scripts
