fix: use minimal CLI for conversation commands only

- Created bin/brainy-minimal.js with only conversation commands
- Fixes 'brainyData.js does not export Brainy' error
- Removed deprecated boolean package warning with override
- Full CLI will be restored in 3.20.0

This is a temporary fix to ensure conversation setup/remove work
while we refactor the complete CLI system.
