dsh-llm-network-retry: Keeping a conversation alive during network outages

`dsh-llm-network-retry` is a DSH plugin maintained by elfgzp that implements the `unbounded_connection_retries` rule from Codex CLI: it retries connection failures (TRANSPORT/TIMEOUT/NETWORK) without limits, starting at 5 seconds and doubling up to 60 seconds, while keeping other errors bounded; actual 400 errors, authentication failures, or context overflow still fail immediately. It hooks into the retry waterfall of the agent loop at the same extension point as the built-in `llm-retry`, executing via `prepend` to prevent double reconnection chains. It works out of the box without any configuration, but also offers three presets (`codex/always/normal`) and optional configurations such as backoff and scope. Additionally, the plugin handles the interruption caused by process crashes: it marks scan sessions on startup and automatically resumes sessions upon reopening, without blind replaying and to prevent restart loops. It is suitable for long-running task scenarios frequently affected by network switching. Before installation, users should check the source code and license (MIT). The plugin only covers failures at the model request layer.
