Fixes + UX: combat HP, char delete, dice animation, compendium filters, import/export
- Combat: relabel HP controls Dmg/Heal, disabled at 0 (were silent no-ops)
- Characters: per-card Delete (confirm) + Export; header Import from JSON
- Dice: tumbling roll animation that settles on the result (a11y-safe)
- Compendium: per-category filters (monster type/CR, spell level/school, item rarity/type) + Clear
- Character import/export to portable JSON (reassigns id, validates on import)
- New: 4 io unit tests, e2e fixes spec (HP damage, delete, CR filter)
