Follow-up to #354. Updates the useChat reference for how a send or an answer ends in 0.6.0, and adds the server-route examples that were waiting on it.

Wording

• The Backend calls closing paragraph is split in two, with no colons. The first part says to forward each request and return its result, and when a failure sets error. The second covers Next.js server actions, which should wait a few seconds for a refusal and then resolve.
• The Returned actions and Questions intros said "a failure sets error". They now say it's set when Base44 refuses the request, or when the backend fails before Base44 has the prompt or answer. A question reopens only in that case.

Examples

• sendMessage() has two tabs. One is a route handler that forwards the request. The other is a server action that races the request against 3 seconds and logs a failure that arrives later, modeled on waitForRefusal in base44-platform-starter.
• submitToolCallInput() has a route handler that forwards tool_call_id, action, and extra_user_input. extra_user_input is now a documented field on Submit tool-call input, and message_id stays private, so the example leaves it out.

Each route checks in a comment that the signed-in user may use the app before forwarding anything.

All three examples type-check in strict mode. npm test in packages/platform passes, and the docs build has no warnings.

After this merges, the Platform SDK reference needs regenerating in mintlify-docs. @base44/platform 0.6.0 is already published.
