feat: Complete database schema support for authentication

jonathanpeterwu · jonathanpeterwu · commit 2bb23b58dedf · 2026-01-19T11:04:45.000+04:00
- Added password_hash column to users table in both PostgreSQL and SQLite
- Added migrations (v4 for PG, v3 for SQLite) to add password_hash column
- Made email field UNIQUE in users table for both databases
- Updated CLI version from 0.3.17 to 0.3.20 to match package.json
- Database now fully supports signup and login authentication flow

This completes the authentication infrastructure requested for the Railway API.
