dsh-damage-pulse: DSH Damage-Style Token Balance Monitoring

dsh-damage-pulse is a DSH client plugin that provides a damage-style balance animation within the Web interface, peak-valley billing, session cost statistics, and a desktop companion character "Jingyuniang." After each model call, it inserts a token detail line, and the input area displays the session's cumulative usage. The balance floating window reflects real-time deductions, distinguishing between cache hits and misses. It includes built-in DeepSeek pricing rules for 2026-08-23, supporting API Key configuration and HTTP endpoint queries. Installation command: `dsh plugin --profile web add github:wssfk12138/dsh-damage-pulse`, requiring DSH version 0.1.1-rc.2 or above.
