Suuntool v0.8.0 hardens MCP integration: downsamples workouts_sml streams to fit the 1MB message cap and rejects unknown workouts_extensions types on arrival.

Why it matters: Prevents workouts_sml streams from exceeding the 1MB MCP message cap; enforces known extension types. Test MCP integrations if you stream high-volume workout data.
