Added always-visible crit threshold display with +/- adjustment buttons to Attack Roll and Spell Cast dialogs in Foundry VTT v13. Key implementation: store critThresholdModifier as relative adjustment (not absolute), use Math.clamp (not deprecated Math.clamped), reset modifier when weapon/spell changes, pass effective threshold to attackCheck()/skillCheck(). Files: attack-roll-dialog.mjs, spell-cast-dialog.mjs, rolls.mjs, templates, SCSS.
