#311

What to build

Allow a workflow node to launch and supervise an OpenCode coding session, collect declared outputs when its turn completes, and expose the session and attempt from the run view.

Acceptance criteria

Agent nodes launch through the existing platform/session launch service rather than a second launch path.
Fresh sessions are the default and are linked to the workflow run, node, and attempt.
An explicit session-affinity key can reuse a compatible session across related attempts.
Session idle/terminal state completes the attempt without requiring a special agent completion tool.
Final-message, Git-diff, file, and JSON-file collectors are supported and validated.
The run view links to the agent session and displays its current and terminal state.
Workflow cancellation delegates to existing session cancellation and records the result.
Platform/host capability handling remains generic; frontend code does not branch on platform identity.
A sequential approval-to-agent workflow is verified through the workflow-run harness and thin transport tests.
