fix(tauri): sync native app version with package releases (#257)

## Summary
- sync the Tauri native version metadata from
`packages/tauri-app/package.json` so release builds pick up workspace
version bumps like `0.13.1`
- update the checked-in Tauri `Cargo.toml` and `tauri.conf.json`
versions from `0.12.3` to `0.13.1`
- document the prebuild sync behavior in `BUILD.md`

## Testing
- `node packages/tauri-app/scripts/sync-tauri-version.js`
