- WebUI sidebar/login display and OneBot get_version_info now read the
root package.json version via Vite `define`, removing hardcoded
literals in webui/src/types.ts and core/onebot/actions/info.ts.
- tools/bump-version.mjs (exposed as `pnpm bump <ver>`) syncs the
version field across the root and all five workspace packages.
- Bump everything to 1.7.8.
