- Create data/disciplines/elemental-regen.ts (base + utility elements)
- Create data/disciplines/elemental-regen-advanced.ts (composite + exotic)
- Wire into ALL_DISCIPLINES via index.ts and discipline-slice.ts
- Add perElementRegenBonus to ComputedEffects type
- Merge regen_{element} discipline bonuses in computeAllEffects()
- Apply per-element regen to element mana each tick in gameStore
- Add 'Elemental Regen' and 'Advanced Regen' tabs to DisciplinesTab UI
