Define and implement a provider-agnostic progress/event pipeline so IdeA can expose as much non-terminal activity as each AI profile makes available before Final. Scope includes a canonical event taxonomy for chat/delegation flows, mapping from profile-specific adapters (Codex, Claude, OpenAI-style structured, and future profiles), and transport/projection rules that preserve robustness when some profiles expose little or no intermediate output.
