What typically restarts automatically during local Bolt development when you edit code?

When a Bolt project is being developed locally through the current Slack CLI, `slack run` can watch application files and automatically restart the local application development server when supported source files change. Slack documents this behavior for Bolt for Python and Bolt for JavaScript projects. Python projects normally watch `.py` files, while JavaScript projects watch `.js` files unless the developer customizes the watch configuration. This live-reload capability shortens the development cycle because developers can modify application logic and have the running process restarted without manually stopping and relaunching it after every edit. The Slack workspace itself is not restarted, the user's browser is unaffected, and OAuth tokens are not regenerated merely because source code changes. Therefore, B is correct.
