Flow State Tracker - Web Mock CLI Tool

The 'flowstate' tool is implemented entirely in a single HTML file, leveraging HTML, CSS, and JavaScript. It presents a terminal-like interface to the user, complete with a command prompt, output log, and visual elements mimicking a terminal window. The JavaScript handles command parsing, state management for the focus timer (running, paused, task details, elapsed time), and interaction with the browser's local storage to save and retrieve session history. It supports commands like 'flow start', 'flow pause', 'flow resume', 'flow stop', 'flow status', 'flow stats', 'flow reset', and 'clear'. The interface includes visual feedback for the timer's progress and momentum. The code also includes a demo mode that seeds the interface with example output and session history upon initial load.
