…d standalone Wrap the astabench imports and astabench-dependent re-exports in try/except ImportError so submodules that don't need astabench (e.g. agent_baselines.solvers.inspect_swe) can be imported in environments where astabench isn't installed. No behavior change when astabench is installed.

Summary
agent_baselines/solvers/__init__.pyimportsastabench.util.modelat module top, so importing any submodule (e.g.agent_baselines.solvers.inspect_swe.agent) requiresastabenchto be installed in the venv.Some solvers under
solvers/are independent ofastabench(the inspect_swe wrapper,llm_with_prompt). Wrapping the astabench-touching imports intry/except ImportErrorlets those solvers be used from minimal environments that don't pull in astabench's transitive deps (e.g. an inspect_swe-only setup that needs newerlitellmthanastabench==0.5.xpins).No behavior change when astabench is installed.
Test plan
python -c "from agent_baselines.solvers.inspect_swe.agent import inspect_swe_solver"succeeds. (On main it raisesModuleNotFoundError: No module named 'astabench'while loadingsolvers/__init__.py.)futurehouse_solver,llm_with_prompt,normalize_model_name,record_model_usage_with_inspect) import the same as on main.
