fix(bridge): 0x7E iZotope — append core DLL dirs (Program Files/iZotope/*/Cores) vao PATH truoc Module::create

iZotope VST3 single-file (Ozone 11.vst3) reference core DLL (iZOzone11Core.dll) dat rieng o C:\Program Files\iZotope\<Product>\Cores, khong canh .vst3. SetDllDirectoryW chi phu dir canh plugin -> LoadLibraryW fail ERROR_MOD_NOT_FOUND (0x7E) -> Windows dialog khi app load plugin. VstDllSearch.h quet cac dir Cores co dinh + append vao PATH (process-global, bridge load 1 plugin 1 luc). Ap dung ca RenderFxJob (FX chain + scan) va Vst3Instrument (VSTi).

+// iZotope VST3 (Ozone 11, Nectar, Neutron...) là single-file .vst3 — core
+// DLL (vd iZOzone11Core.dll) nằm RIÊNG ở
+//   C:\Program Files\iZotope\<Product>\Cores
+// KHÔNG cạnh plugin → LoadLibraryW của VST3 SDK fail ERROR_MOD_NOT_FOUND
+// (0x7E) dù setPluginSearchPath đã trỏ dir cạnh plugin. Helper này quét các
+// dir Cores cố định và thêm vào PATH (process-global — bridge load 1 plugin
+// 1 lúc, giống SetDllDirectoryW hiện có).
