- Added new environments for reinforcement learning, including `HermesSweEnv` for software engineering tasks and `TerminalTestEnv` for inline testing. - Introduced `ToolContext` for unrestricted access to tools during reward computation. - Updated `.gitignore` to exclude `wandb/` directory. - Enhanced `README.md` with detailed architecture and usage instructions for Atropos environments. - Added configuration files for SWE and terminal test environments to streamline setup. - Removed unnecessary compiled Python files from `__pycache__`.
