/migrate

What

The single migration workflow for three change types, with EF Core schema migrations as the primary flow:

1. EF Core schema — review pending model changes, generate a descriptively named migration, review the SQL for data loss and locking risks, apply with a documented rollback path.
2. .NET version upgrade — phased TFM/SDK/package upgrade with verification at each phase.
3. NuGet updates — incremental, one-package-at-a-time updates so breakage is always attributable.

Shared principles: verify before applying, rollback plan always, test after every step, one logical change per migration.
