dsh-ocr-seam-guard: Automated Repair Guard for the DeepSeek Harness OCR Plugin

`dsh-ocr-seam-guard` is a guard plugin developed by DosterBool, designed to automatically repair the `dsh-ocr` patch when it is overwritten during DeepSeek Harness upgrades. It automatically restores critical code at startup by monitoring the adapter seam, enforcing UTF-8 output, and correcting the API interface. The plugin features anchor drift tolerance, load verification, and rollback mechanisms, supports globally installed npm environments, and ensures the consistency of the OCR service environment.
