feat(rules): alignment-gated spell damage for Shard of Chaos and Spear of Purity

DamageEffect gains an optional AlignmentGate (axis law_chaos/good_evil):
the immune side (chaotic/good) is wholly unaffected (no damage dice rolled),
neutral-on-axis targets take half damage with no condition (gate halving
stacks after the save halving), and the full side (lawful/evil) takes full
damage plus the gate condition on a failed save. Shard of Chaos maps the
SRD slowed to the engine staggered condition (the -1 penalty and half-speed
of slow are not modeled); the outsider-only 1d6/level variants are not
modeled (no outsider subtype). Non-gated damage spells are bit-identical.
Loader validates axis/side pairing with clear ValueErrors.

"description": "SRD spells/shard-of-chaos.md: evocation [chaotic], level 2 (cleric/oracle/warpriest), range close, dart-shaped projectile of chaotic energy delivered as a ranged touch attack, Will partial, spell resistance yes. A lawful creature struck takes 1d8 points of damage per two caster levels (maximum 5d8); a successful Will save halves the damage. Simplified: the engine has no alignment track, so the SRD alignment gate (no effect on chaotic creatures, half damage to neutrals, the lawful-outsider 1d6/level + slowed variant) cannot be represented - the base 1d8-per-two-levels damage (engine floor: caster_level // 2 dice) is modeled against every target as force damage (no energy type models chaotic energy), Will half."
"description": "SRD spells/shard-of-chaos.md: evocation [chaotic], level 2 (cleric/oracle/warpriest), range close, dart-shaped projectile of chaotic energy delivered as a ranged touch attack, Will partial, spell resistance yes. A lawful creature struck takes 1d8 points of damage per two caster levels (maximum 5d8) and, on a failed Will save, is slowed for 1 round; a successful Will save halves the damage and negates the slow. The bolt has no effect on chaotic creatures (alignment_gate immune) and deals only half damage to creatures neither lawful nor chaotic, without the slow (alignment_gate neutral halving). Simplifications: the SRD's slowed condition is mapped to the engine's staggered condition (the SRD slow entry states a slowed creature is staggered; the -1 penalty and half-speed parts of slow are not modeled); the lawful-outsider variant (1d6 per caster level, maximum 10d6) is not modeled (the engine has no outsider subtype); force damage stands in for chaotic energy (no energy type models it)."
