Lean 4 agentic theorem proving: a thin per-dataset wrapper over the shared verifiers.v1.tasksets.lean base, which plants a sorry starter proof in a Mathlib sandbox and rewards a clean lake env lean compile (with a guard pinning the theorem statement). Needs a container runtime.

Changelog
- 2026-09-03: Restore default solver network access by reverting the
network_allow=[]default-deny policy introduced in #780; training rollouts need outbound network. - 2026-08-31: Yield task records on demand so bounded evaluations construct only the requested prefix.
- 2026-07-29: Split out of the
lean_v1bundle into its own environment (one dir per taskset,environments/lean/group). - 2026-07-10: Ported to the task-centric verifiers API: rewards and lifecycle hooks live on the
Task(aTaskDatarow + behavior split), and task-facing config knobs (judges, tool/user placement, scoring parameters) moved from--env.taskset.*to--env.taskset.task.*. Requiresverifiers>=0.2.0and Python>=3.11.
