Add workspace review summaries

Add workspace summary across the CLI, SDK, and MCP, and include it in the workspace-core profile so chat hosts can review one concise view of the current session.

Persist lightweight review events for syncs, file edits, patch applies, exports, service lifecycle, and snapshot activity, then synthesize them with command history, current services, snapshot state, and current diff data since the last reset.

Update the walkthroughs, use-case docs, public contract, changelog, and roadmap for 4.3.0, and make dist-check invoke the CLI module directly so local package reinstall quirks do not break the packaging gate.
