v0.41.2February 4, 2026

CRITICAL FIX: Ship purchases now properly persist to database (thanks VexNocturn!)
Root cause: buy_ship only updated in-memory state, not database
After server restart, player's ship_id pointed to a non-existent ship
Fix: buy_ship now uses database transaction (atomic CreateShip + UpdatePlayer)
Added persistence tests to prevent regression
