fix(bridge): deploy ABI-fixed VST2 binary to install + open GUI for VST2 tracks

Qin_RV_x64.dll (Kong Audio) crashed with SEH 0xc0000005 in Bridger64.dll
using the stale install binary (pre-ABI-fix). Copy native_bridge build
Release binary into install/ so the packaged app runs the fixed host.

Also open the native GUI after loading a VST2 instrument (previously
VST3-only), so Qin_RV's editor (Qin_VST_Window via auxhost.exe) shows
automatically on track load.
