refactor: enrich provider turn stream model

Add turn-stream capability metadata and richer normalized provider events for reasoning blocks, tool lifecycle, and turn boundaries. Track those signals in turn execution state and cover the new Copilot adapter/state behavior with tests. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
