fix: 6 priority-3 bug fixes with regression tests

- Issue 83: Mana Tide pulse factor now ranges 0.5x-1.5x (was 0.5x-1.0x)
- Issue 82: SteadyStream no longer returns early like EternalFlow; only skips incursion penalty
- Issue 81: Prestige store partialize now includes defeatedGuardians, signedPacts, signedPactDetails, pactRitualFloor, pactRitualProgress, loopInsight, pactSlots
- Issue 80: Combat store partialize now includes floorHP, floorMaxHP, castProgress, spireMode, clearedFloors, golemancy, equipmentSpellStates, activityLog, achievements
- Issue 78: cancelDesign now always cancels designProgress first, then designProgress2
- Issue 79: startDesigningEnchantment now uses designProgress2 when designProgress is occupied

Added 13 regression tests in src/lib/game/__tests__/regression-fixes.test.ts
Refactored craftingStore types to craftingStore.types.ts to stay under 400-line limit
