Fixed double effect application in Foundry v13 - createEmbeddedDocuments auto-prepares data, manual prepareData() caused effects to apply twice. Added crit threshold clamping in prepareDerivedData since schema min/max constraints don't apply to effect-modified data. Tests verify skill and attack crit thresholds work with Active Effects.
