- mosaic-init bash script: detect existing SOUL.md/USER.md/TOOLS.md and
prompt user to keep, import (re-use values as defaults), or overwrite.
Non-interactive mode exits cleanly unless --force is passed.
Overwrite creates timestamped backups before replacing files.
- launch.ts checkSoul(): prefer 'mosaic wizard' over legacy bash script
when SOUL.md is missing, with fallback to mosaic-init.
- detect-install.ts: pre-populate wizard state with existing values when
user chooses 'reconfigure', so they see current settings as defaults.
- soul-setup.ts: show existing agent name and communication style as
defaults during reconfiguration.
- Added tests for reconfigure pre-population and reset non-population.
