Japanese Walking

Japanese Walking is a simple interval walking app for Garmin watches inspired by Japanese interval walking training. The workout alternates between fast and slow walking blocks and keeps the session readable at a glance with a large countdown timer, a phase icon, and a section ring around the edge of the watch face. During the workout, the app shows: - Remaining time in the current phase - Total workout time - Distance - Heart rate - Calories - Section progress When the workout is saved, the app records a FIT activity as `Japanese Walk`. On supported watches, GPS is enabled during the workout to improve route and map data.

Added a Warmup and Cooldown section (enabled by default, but can be disabled in settings)
