v1.4.0 — The Complete AI Migration Assistant

MigraDiff v1.4.0 turns the PostgreSQL schema-diff tool into a complete
AI-powered migration assistant. Four schema-aware AI flags, all optional —
the core diff engine stays dependency-free.

Added

• --explain — plain-English explanation of any migration
• --rollback — generates a reversal migration for a given diff
• --advise — deterministic + AI risk assessment of a migration
• --generate — writes a migration from a plain-English description,
  using your real table names and column types from a
  live connection or schema file

Safety

• --generate hard-refuses bulk-destructive requests ("drop all",
  "wipe", etc.) before any API call is made
• Soft-warns and flags individual destructive operations
• All AI output is marked as AI-generated; temperature 0 for determinism
• --generate is combinable with --advise for immediate risk feedback

175 tests passing. AI features require an Anthropic API key:
