- Remove deprecated 'query' command (replaced by 'db-query')
- Remove deprecated 'schema' command (replaced by 'db-schema')
- Remove 4 obsolete tests that tested deprecated functionality
- Update all remaining tests to use new db-prefixed command names
- CLI now has clean, consistent command structure with proper prefixes
- All 478 tests passing after cleanup
This completes the CLI consistency convention implementation where all
subsystem commands follow the "*-stats" pattern and use proper prefixes.
