Add AI sidekick command

This commit introduces a new feature where an AI sidekick can assist with tasks. The AI sidekick is initialized with a set of tools for file management and human input. The sidekick can be invoked via the new `sidekick` command in the CLI.

Additionally, the `review` command has been updated to clarify that it can review either unstaged changes or a specified commit. The help text for the `--commit` option has been updated to reflect this.

Minor changes have also been made to the `get_llm_model` function to allow for a default token size.
