SpringDAOT: All Features

**Fixed Issues:**

**Rank System:**
- Fixed rank progression logic - now correctly checks kill requirements
- Fixed `/rank setKills` command to properly recalculate rank and progress instead of resetting to 0
- Fixed `/rank up` command to bypass kill requirements for admin use
- Added automatic rank up notifications when reaching required kills

**2-Step Titan Transformation:**
- Fixed transformation to recognize custom titan types (attack_2, beast_2, warhammer_2, etc.) assigned via `/daot shifter`
- Players without a titan power assigned now get an error message instead of failing silently
- Uses Danny's mod's transformation system via reflection, allowing the existing mixins to spawn the correct custom titan based on player tags
- Press N twice now properly transforms into your custom titans
