DeepSeek Harness Plugin: dsh-token-ledger-pro (DSH Cost Analytics and Token Ledger)

`dsh-token-ledger-pro` is the billing plugin for DeepSeek Harness, created by merging the original billing panel and overhead statistics. It provides automatic token usage collection, real-time display of costs and balances, budget alerts, and Chinese-English bilingual support. The plugin includes built-in pricing catalogs for 16 vendors, supports DeepSeek’s peak and off-peak pricing, and enables custom HTTP balance queries. Data is persisted in local JSON files, and historical records and configuration details can be queried via API, effectively addressing cost-tracking pain points in multi-model development.
