DeepSeek Harness Plugin: dsh-peak-pricing-warning

This plugin provides real-time cost management for DeepSeek Harness, displaying pricing window status, countdown, and session cost estimates in the interface. It uses UTC time to distinguish peak, off-peak, and weekend periods, and calculates costs based on DeepSeek's four billing buckets. It indicates status with colors, helping developers accurately plan API costs. Installation requires a Git URL; token counting and mid-session model switching are not supported.
