# Run Alembic migrations, then start the server.
# Seed categories/laws as well so a fresh DB has reference data.
# Startup:
# 1. Create base tables (no-op if they exist) — handles fresh Postgres DBs
# 2. Stamp alembic head so migrations know baseline was just created
# 3. Run any migrations after head (no-op on first boot; applies new migrations on subsequent deploys)
# 4. Seed reference data (categories, laws)
# 5. Start server
