Code Review
The pull request introduces significant new features to the Heidi CLI, including comprehensive HuggingFace model management (search, download, compare, analytics, removal), enhanced model hosting with OpenCode API integration, true streaming response capabilities, and detailed model metadata and metrics tracking. The CLI also gains new commands for interactive setup, configuration display, memory search, and advanced registry management (listing versions, showing info, and rollback). The evaluation harness has been substantially expanded with multiple tasks and a promotion policy. However, the review highlights several critical issues: runtime state and log files are incorrectly committed to version control with hardcoded absolute paths, important ruff and pytest configurations were removed from pyproject.toml, the local model streaming implementation is not truly streaming as it processes the full response before chunking, the hot-swapping logic is incomplete and does not trigger a model reload in the running server, and the hf_compare function is overly complex and requires refactoring into smaller, more focused helper functions.

This file and others under the state/ directory (state/logs/model_host.log, state/registry/pids.json) appear to be runtime state, configuration, or log files. These types of files should not be committed to the version control system as they are specific to a local environment and will change during application execution.
Additionally, this file contains a hardcoded absolute path ("data_root": "/home/ubuntu/heidi-cli/state"), which makes the application not portable.
Please remove the state/ directory from the repository and add it to your .gitignore file. The application should be responsible for creating these directories and default files at runtime if they do not exist, and paths should be derived dynamically or be relative.

The configurations for ruff and pytest have been removed in this change. These tools are important for maintaining code quality and ensuring tests are run correctly. If this removal was unintentional, please restore the [tool.ruff] and [tool.pytest.ini_options] sections.

This implementation of _stream_local_response does not perform true streaming. It awaits the full response from get_response and then splits the completed text into chunks. This defeats the primary purpose of streaming, which is to reduce the time-to-first-token.
To fix this, you should use the streaming capabilities of the underlying transformers library, for example by using a TextStreamer instance with the model.generate call to yield tokens as they are generated.

The hot-swapping logic appears incomplete. While this function updates the registry file to point to a new stable model, it doesn't trigger a reload of the model in the currently running model_manager instance. The model_manager only loads the model from the registry upon initialization.
For hot-swapping to work, the running server process needs to be notified of the change. Consider implementing a mechanism such as a dedicated API endpoint for reloading, or using process signals (e.g., SIGHUP) to trigger the model_manager to re-read the registry and load the new model.

The hf_compare function is quite long and handles multiple responsibilities: fetching data, building a rich table, and generating recommendations. To improve readability, maintainability, and testability, consider refactoring this into smaller, more focused helper functions. For example:
_fetch_models_info(hf, model_ids)to handle data fetching and error handling._build_comparison_table(models_info)to construct therichtable._generate_recommendations(models_info)to determine the best models based on different criteria.
