fix(rules): ray of enfeeblement applies a rolled Strength penalty (Fort half) instead of fatigued

SRD ray-of-enfeeblement.md: 1d6 + 1 per 2 caster levels (max 1d6+5) Strength
penalty, Fortitude half, 1 round/level. Adds a PenaltyEffect type (rolled
formula, scaling, half on save, level-scaled duration) applied as negative
untyped modifiers on the rolls Strength feeds (attack, damage), since the
engine has no ability-score track. Formerly modeled as a fatigued condition
with Fort negates.

Simplification: the engine has no ability damage, so the Strength penalty is modeled as the fatigued condition (attack/damage penalties, no charge) for 4 rounds (1 round/level at caster level 4); Fortitude halves is approximated as Fortitude negates."
