fix: open links in browser for /help and chat responses

Links in chat responses were not opening because:
1. Link URL was being read from wrong JSON path (node.link instead of node.params.link)
2. Was delegating to LSP server which has empty handlers

Now opens browser directly on client side with correct URL extraction.
