dsh-multiprovider: DeepSeek Harness Multi-Account Scheduling and Health Management Plugin

`dsh-multiprovider` is a plugin for DeepSeek Harness that allows multiple sets of credentials to be managed under a single Provider abstraction. It is maintained by monotykamary, released under the MIT License, and supports account polling, weighted scheduling, session affinity, and health monitoring. Core features include deterministic scheduling policies, normalized failure classification, configurable cooldown strategies such as exponential backoff, and account weight management through the settings interface. Credentials are stored using opaque references and are not directly exposed as keys. Installation requires Node.js 22+ or 24+, pnpm 11, and DSH 0.1.1+. To use it, register a Provider Inventory to define accounts, obtain a lease via `acquire`, and explicitly release it after the operation is completed.
