  test_agent_loop, test_agent_loop_vllm, test_agent_loop_tool_calling,
  test_terminalbench2_env_security

  setup block, and rl_training post-setup handler
- tools/budget_config.py: remove RL environment reference in docstring
- tests/test_model_tools.py: remove rl_tools from expected groups
- tests/run_agent/test_streaming_tool_call_repair.py: fix stale cross-reference

- Remove yc-bench extra
- Remove rl_cli from py-modules
- Remove [tool.ty.src] exclude for tinker-atropos

- nix/hermes-agent.nix: remove tinker-atropos pip install line

* chore: remove RL references from cli-config.yaml.example

- hermes_cli/doctor.py: remove Submodules check section (tinker-atropos)
- hermes_cli/setup.py: remove RL Training status check
- hermes_cli/status.py: remove Tinker + WandB from API key status display
- agent/display.py: remove both rl_* tool preview/activity blocks
