fix: make discipline perk numerical bonuses functional via structured BonusSpec

- Add PerkBonus type and optional bonus field to DisciplinePerk
- Populate bonus data on 39 perks across base, elemental, elemental-regen,
  elemental-regen-advanced, and invoker discipline files
- Rewrite computeDisciplineEffects() to apply once/infinite/capped perk bonuses
  through known stat keys (maxManaBonus, baseDamageBonus, regen_*, elementCap_*)
- Add per-element cap bonus routing in effects.ts computeAllEffects()
- Remove dead enchantPower bonus (no consumer in effects pipeline)
