Initialize Warehouse Schema

Generate a comprehensive, user-editable schema reference file for the data warehouse.

Scripts: ../analyzing-data/scripts/ — All CLI commands below are relative to the analyzing-data skill's directory. Before running any scripts/cli.py command, cd to ../analyzing-data/ relative to this file.

What This Does

1. Discovers all databases, schemas, tables, and columns from the warehouse
2. Enriches with codebase context (dbt models, gusty SQL, schema docs)
3. Records row counts and identifies large tables
4. Generates .astro/warehouse.md - a version-controllable, team-shareable reference
5. Enables instant concept→table lookups without warehouse queries
