The main @libsql/client entry point pulls in the native libsql module
and isomorphic-ws/isomorphic-fetch, which webpack cannot parse in
EdgeOne builds. Using the http subpath provides a pure HTTP client
that works in edge/serverless environments without native dependencies.
Also add libsql, @libsql/isomorphic-fetch, @libsql/isomorphic-ws to
the edge build alias list in next.config.js as a safety net.
