Module shard 

Shard command for extracting tenant-specific data from SQL dumps.

The shard command extracts data belonging to a specific tenant by:

• Identifying tables with the tenant column (tenant roots)
• Following FK chains to include dependent data
• Including junction/pivot tables where any FK matches tenant data
• Optionally including global/lookup tables

Supports MySQL, PostgreSQL, and SQLite dialects.
