dsh-whale-meter: DeepSeek Harness Usage and Cost Dashboard

dsh-whale-meter is a community-maintained DeepSeek Harness (DSH) plugin designed to provide a centralized usage and cost dashboard. Developed by Shiye-10Pages under the MIT license, it supports local computation with zero data reporting, only initiating network requests when querying balances. Its core features include multi-model cost estimation (covering 46 models such as DeepSeek, Anthropic, and OpenAI), monthly consumption tier display, daily budget reminders, and price comparison and peak-valley pricing before and after the August 17 DeepSeek price adjustment. Additionally, it supports per-model/session billing, historical data backfilling, 14-day trend analysis, and balance queries. The installation is simple, enabling activation via the `dsh plugin add` command.
