dev.sh now runs preflight checks (build backend, build desktop,
wails generate module, npm install + tsc) before starting wails dev,
so type errors and binding mismatches surface immediately. Adds
download-adb.sh for fetching platform ADB binaries to embed in
distribution builds.
Sets up monorepo with Wails desktop shell, Go backend, React/TS frontend, and Kotlin Android SDK skeleton.
