Crown Cosmos Callout

v1.23 - Detection fixed for Crown of the Cosmos's Silverstrike Arrow private aura. v1.22 was tainting on the player's own aura because it read aura.spellId off updateInfo.addedAuras and private-aura fields are protected. v1.23 uses C_UnitAuras.GetPlayerAuraBySpellID(1233602) as a truthy-only check from both UNIT_AURA and a 0.2s polling fallback - no aura field is ever read, so taint can't propagate. Encounter-ID gating (3181 = Crown of the Cosmos per DBM) now silences the addon outside the boss, so /reload mid-pull can't announce on a later wave and stray addon messages can't prime our state. /ccc test live updated to call the detection callback directly. No protocol break.
