Android plugin restructure: link local plugin, update Gradle include, Vite alias, and gitignore

- package.json: use link:./capacitor-plugins/betaflight-serial
- vite.config.js: alias to local plugin ESM
- .gitignore: ignore capacitor-plugins/*/android/bin/
- android/capacitor.settings.gradle: include :capacitor-plugin-betaflight-serial at ../capacitor-plugins/betaflight-serial/android
- ran yarn android:sync to update settings
