The suggest tool's renderer was never dispatched by the TUI. It fell through to the generic tool fallback, so users saw a raw ⚙ suggest [suggest=…] line instead of the suggestion bar, and the action buttons never appeared. The fallback only prints primitive parameters, which drops the actions array.

This connects the existing Suggest renderer in the session route and passes it the live suggestion request. The request is matched by session, message ID, and call ID, so a tool part only shows its own suggestion. The renderer itself is unchanged.

The built-in tool emits non-blocking suggestions, which the footer intentionally skips. That left the tool part as the only place these suggestions could render.

The added test guards that suggest is recognized by the dispatcher. It does not cover the route-level request matching, which would need a full session-route harness.
