* Insert paragraph separator between Copilot CLI assistant messages
When the CLI emits multiple assistant messages in a single turn, each
message arrives as its own `assistant.message_delta` /
`assistant.message` event with a distinct `messageId`. The handlers
forwarded each event to `stream.markdown(...)` with no separator, so
consecutive messages fused into a run-on paragraph
(e.g. "...wiring:Now add...").
Track the last emitted `messageId` and prepend `\n\n` whenever the
incoming event carries a different (defined) id. Streaming deltas
sharing the same `messageId` remain unaffected.

* Add regression test for undefined messageId legacy behavior
Addresses Copilot review feedback: lock in that legacy SDK emissions
without a defined messageId continue to be concatenated without an
inserted separator, rather than producing spurious blank paragraphs.
