SQLAlchemy 1.4 -> 2.0 migration tool for repetitive legacy patterns

I built a scanner-first SQLAlchemy 1.4 -> 2.0 migration tool for a narrow documented subset of legacy patterns.

It is intentionally not a full "AI migration" promise. It handles supported patterns like:

• select([..])
• session.query(Model).get(pk)
• simple string relationship joins
• simple string loader options
• legacy declarative imports
• simple DML constructor keyword rewrites

Unsupported patterns stay visible in a manual-review bucket, so the free scan can tell you whether a repo is even a fit before you pay for anything.
