Module database_validator 

Compile-time database validation for schema definitions.

Validates a compiled schema against a live database at three levels:

• L1: sql_source relation exists in the database
• L2: Columns and JSON column types match
• L3: JSONB keys exist in sampled rows (best-effort)

All diagnostics are warnings — compilation never fails due to validation.
