dsh-qualityforge: Systematic QA and Actionable Fix Proposals

QualityForge is an enterprise-grade QA plugin within the DSH ecosystem, designed to address verification blind spots and record loss during code delivery. It provides an enterprise-grade test methodology library covering 45 domains and 1,363 test cases, and supports four levels of depth, project-type awareness, and an evidence-first strategy. The plugin uses commands such as `qf_scan`, `qf_plan`, and `qf_exec` to build a standardized pipeline and generate checkbox-enabled Markdown reports. Report results can be written back to project data, and `qf_fixplan` can generate remediation waves. Its core advantages include a fully read-only workflow, disk-evidence-based operation, security-boundary controls, and converting the QA process into reproducible, negotiable release checklists.
