feat(spells): add spell system with 10 combat spells, cast_spell action
Spells are SpellSpec dataclasses with typed effects: DamageEffect
(dice + types, half-on-save), ConditionEffect (condition lookup +
save negates), HealEffect (capped at hp_max), BuffEffect (transient
StatModifiers). Range categories (personal/touch/close/medium/long)
scale with caster level via spell_range_ft. JSON loader
(load_spell/load_spell_registry) reads data/spells/*.json.
The engine integrates spells via Action(kind='cast_spell') and
_cast_spell: range check, line-of-effect gate, save resolution
(resolve_save), effect application (_apply_spell_effects with DR
via _apply_dr_for_types), transcript logging. The spell_registry
is passed to CombatEngine; Combatant.spells holds known spell names.
- spells.py: SpellSpec, 4 effect types, SpellRange/SaveType literals,
spell_range_ft, JSON loader (uses Json type from foundry.py)
- conditions.py: CONDITIONS_BY_NAME registry for condition lookup
- combat.py: cast_spell Action kind, _execute_cast_spell dispatch,
_cast_spell (range/LoE/save/effects/log), _apply_spell_effects,
_apply_dr_for_types, _save_label helper, SpellSpec/BuffEffect/etc
imports, spell_registry parameter on CombatEngine
- models.py: spells field on Combatant
- data/spells/: 10 spells (Magic Missile, Burning Hands, Fireball,
Lightning Bolt, Acid Arrow, Cure Light/Moderate Wounds, Hold Person,
Fear, Bull's Strength)
- tests/test_spells.py: 29 tests (loading, range, damage/save/condition/
heal/buff/DR, out-of-range, unknown spell, dispatch, DC scaling)
- pyproject.toml: PLR0913 ignore for combat.py (CombatEngine.__init__)
- README.md: spells.py architecture section, Sorts removed from
non-modeled list, 336 tests
