﻿GrandBridge 0.1.116ez Demo V6 beta

VST2 hosting restored and made mandatory for product builds.

Verified before packaging:
- FX VST2 x64: GClip.dll PASS, sample-exact null after reported PDC.
- Instrument VST2 x64: SQ8L.64.dll PASS.
- Instrument VST2 x86: SQ8L.dll PASS through fresh bridge_worker32.exe, real round-trip verified.
- Both product bundles contain x64/x86 worker and scanner helpers in root + both shell templates.

Packaging now aborts if VST2 is disabled or required x64/x86 helpers are missing.
