build(native): rebuild bridge + commit sidecar binary để feature theo push

- fix compile: performEdit dùng setParamNormalized (setParamFromEdit không tồn tại trong SDK này)
- rebuild fx_vst_bridge.exe/daw_vst_bridge.exe/plugin_host.exe (chứa /shm route + SHM audio feeder)
- src-tauri/binaries: hết ignore, commit binary + dll + vst3scan.json — máy khác clone về có ngay feature native
- xóa rác app.precompiled.js.bak + dọn bundle dirs (.bak/.new/_diag/.pytest_cache)
