auto-pwa: AI Wave Analysis Plugin for DeepSeek Harness

The DeepSeek Harness plugin `auto-pwa` uses AI to streamline the tedious manual configuration and iterative fitting workflows in partial wave analysis (PWA) for particle physics. It supports PDG resonance table queries, strict physics gate checks, an integrated ctpwa fitting engine, and SLURM cluster job submission. Users can run it via an interactive interface or in headless mode, with capabilities for automatic iterative convergence and numerical diagnostics. The plugin is open-sourced under the MIT license and can be installed globally via npm.
