feat: Implement lesson generation feature and update status display

- Added functionality to generate lessons based on code reviews, including prompts and instructions for the reviewer. - Updated the `.gitignore` to exclude lesson documentation files. - Removed the `/lesson` command from the help menu and command parsing. - Enhanced the status bar to display a message when a lesson is being generated. - Introduced a new `lesson_running` state to track lesson generation progress. - Updated various components to handle the new lesson generation workflow, including subagent events and token usage tracking.
