WaCk/JScrambler JavaScript obfuscation

Wave 3 @emcd-vue/[email protected] (137.5 KB, entropy 5.04) uses WaCk/JScrambler-style obfuscation: 811-element string array (a0c()) backed by a custom lowercase-first base64 alphabet, integer arithmetic to compute array indices, 5-argument helper proxy functions, and an anti-debug self-checking loop. The 6.4.9 re-publish (13.3 KB) applies the same structure more lightly, enabling static recovery. This is a step beyond the obfuscator.io + custom-alphabet layers used in Wave 2 of the same campaign.
