Extend the injection effect in AssistantMessage to also append a ▾ trigger
after inline <code> elements whose text is a browser-localhost or remote URL,
so AI-written run URLs like \`http://localhost:9527/\` get the same open-with
menu that markdown <a> links already receive.

Wire L1 link routing into assistant message rendering. AssistantMessage now
accepts an optional sessionId and, when present, builds an onLinkClick that runs
handlePreviewLink against the running local server base (getServerBaseUrl) and
the browser/workspace panel stores, preventing default on handled links.
MessageList passes sessionId through in the assistant_text case.
Adds getServerBaseUrl() to desktopRuntime as a synchronous wrapper over the api
client's cached getBaseUrl().
