fix: add missing enchantment effects for rotTouch, soulRend, master, and legendary spells

- Add spell_rotTouch to BASIC_SPELL_EFFECTS (death element Tier 1)
- Add spell_soulRend to TIER2_SPELL_EFFECTS (death element Tier 2)
- Add spell_cosmicStorm, spell_heavenLight, spell_oblivion, spell_deathMark to TIER3_SPELL_EFFECTS (master spells)
- Create legendary-spells.ts with spell_stellarNova, spell_voidCollapse, spell_crystalShatter (legendary spells)
- Update spell-effects/index.ts to include LEGENDARY_SPELL_EFFECTS in SPELL_EFFECTS

Closes #41
