S05: runtime work-item driver

Stack Role

This draft PR reserves the S05 review slot in the workflow-owned merge, retry, scheduling, and recovery migration stack. It is intentionally a handoff artifact, not the completed implementation for this slice.

Milestone

Runtime

Depends On

S1 workflow work items, S3 generic scheduler claim path, and S4 built-in IR regions.

Goal

Let WorkflowTaskRuntime start from a workflow work item and persist node/work-item outcomes.

Expected File Scope

packages/engine/src/workflow-task-runtime.ts; workflow graph executor and node handler files; runtime tests.

Expected Tests

Runnable completion, retrying work creation, manual hold creation, restart resume, and duplicate lease refusal.

Exit Gate

Runtime can progress workflow work without old merge queue callbacks.

Full Plan
