npm run migrate references nonexistent migrate.ts #9

What

package.json defines "migrate": "tsx src/database/migrate.ts" but no migrate.ts file exists anywhere under src/database/.

Why

Running npm run migrate would fail with a file-not-found error. Operators have no way to run migrations outside of the Docker entrypoint.

Scope

• Create src/database/migrate.ts that runs the SQL migrations
• Or remove the script if migrations are handled differently

Acceptance Criteria

• npm run migrate works successfully
• Migrations are applied correctly

Technical Context

• File: package.json, line 10
• File: src/database/migrations/001_initial.sql (the migration to run)
