dsh-agy: Google Antigravity OAuth and Multi-Account Pool Plugin for DSH

dsh-agy is a DeepSeek Harness plugin developed by chaos-03x, designed to provide multi-account management, OAuth authentication, rate-limit rotation, and device fingerprint support for Google Antigravity. It features both Web and CLI management interfaces. Its core functionalities include OAuth login support for both browser and headless modes, encrypted multi-account pools, usage-aware automatic account rotation, and intelligent handling mechanisms for errors such as 429 responses. Users can enable the plugin via the `dsh plugin` command on the Web interface or use the CLI in standalone environments through npx/npm. The plugin supports individual proxy configurations for each account and offers detailed error-type response strategies, such as immediate retry for soft limits and cool-down switching for hard limits.
