fix: restore macOS frameworks to tauri.conf.json for proper bundling

TAURI_CONFIG env var merge did not apply frameworks to the bundler,
resulting in libodbc/libltdl missing from Contents/Frameworks/.

Restore frameworks in tauri.conf.json and skip them in dev mode via
build.rs when the dylibs are not present locally.
