Renn F 4c397e1768 feat(gateway): developer i_will_work_on takes a substantive step checklist (#172)
The dev plan was a free string with only a presence gate, so the
executing dev had no checklist for plan-driven progress (#173).

- IWillWorkOnRequest gains `steps` (same SubTask shape as a PM's
  sub_tasks); flow_dev route threads it through.
- i_will_work_on layers steps onto the narrative plan via the same
  panel-shaped path PMs use, so task.plan.sub_tasks is populated
  (panel render + #173 progress).
- New _dev_steps_gate (mirrors _pm_sub_tasks_gate, runs after the spec
  gate): a developer FRESH claim must supply a non-empty steps list
  with every description >= _PM_SUBTASK_DESC_MIN_LEN. Re-entry/recovery
  short-circuit before the gate (extracted _dev_reentry +
  _fresh_dev_claim keep i_will_work_on within the
  return-count + cyclomatic gates).
- developer role prompt: steps template + "thin steps rejected" + the
  progress(plan_step=...) handoff.
- Updated every dev-fresh-claim test fixture across the suite to pass
  substantive steps; added dedicated _dev_steps_gate coverage.

Commit 2 of 3 for the plan/progress quality work (#171/#172/#173).

"""Pin: Choreographer must call task.claim/start with (task_id, agent_id).
Service signatures in ``roboco/services/task.py`` are:
async def claim(self, task_id: UUID, agent_id: UUID, ...) -> TaskTable | None
async def start(self, task_id: UUID, agent_id: UUID | None = None, ...) -> ...
Earlier choreographer code passed (agent_id, task_id) — when the SQL lookup
ran ``WHERE id = <agent_uuid>``, no row matched and the call returned None,
which the choreographer interpreted as "task unchanged". The whole gateway
claim path was non-functional against a real DB. Existing unit tests pinned
the buggy order so the bug stayed invisible.
This test pins the correct order at every Choreographer call site that
forwards into the service.
