Build me a desktop app called Run Coach that connects to Garmin and lets me ask Claude or ChatGPT questions about my health and training.

I want it to sign me in securely, keep my Garmin data local, and then show useful views like a daily morning briefing, trend charts for things like sleep, HRV, resting heart rate, steps, body battery, and training readiness, plus workout details like splits, heart rate zones, and training effect. It should also help plan a training week from my data and let me create or schedule workouts on my Garmin calendar.

Make it feel polished in Claude Desktop and ChatGPT desktop, with interactive charts right inside the conversation and a sidebar view for the main dashboard. If you need to look up current docs or plugin details online, go ahead.
