- toolsets-reference.md: remove rl row + update example
- integrations/index.md: remove RL Training bullet
- architecture.md: remove environments/ from tree + RL section
- contributing.md: remove tinker-atropos setup
- updating.md: remove tinker-atropos install + stale submodule update

* chore: remove remaining RL/Atropos stragglers

- hermes_cli/config.py: remove TINKER_API_KEY + WANDB_API_KEY env var defs
- 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
- website/docs: remove RL references from providers.md + env-variables.md
- tests: remove TINKER_API_KEY from conftest, set_config_value, setup_script

* chore: remove RL training section from .env.example
