Connect game phases, implement gameplay, add lobby commands, remove perks

- Fix GameSession.determineNextPhase() to cycle through all 4 phases
- Implement GameplayPhase with generator tracking and win/lose conditions
- MapBuilder now uses the game world instead of the first world
- Add /dbd lobby (teleport to lobby) and /dbd setlobby (set lobby spawn)
- Remove all perk classes (IPerk, PerkRegistry, 7 perk implementations)
- Fix HexTotem to not reference removed HexRuinPerk
