fix(install): use uclient-fetch and jsonfilter for OpenWrt compatibility

- Replace wget with uclient-fetch (OpenWrt's native HTTP client)
- Replace grep/sed JSON parsing with jsonfilter for reliable parsing
- uclient-fetch returns single-line JSON which broke grep/sed parsing
- Update documentation commands to use uclient-fetch
