Ln 140 Test Docs Creator

This is a specialized worker skill that generates testing-strategy.md and tests/README.md files with a Risk-Based Testing philosophy baked in. It's designed to be called by the ln-100-documents-pipeline orchestrator, though you can invoke it directly if you only need test docs. The skill works in three phases: creates the files from templates, validates structure (SCOPE tags, required sections, POSIX endings), then checks content quality using heuristics from a questions spec. It also auto-discovers your test framework from package.json, requirements.txt, or go.mod to populate project-specific sections. Honest take: this is solid if you want opinionated test documentation that follows a specific pattern (test pyramid, priority thresholds, Story-Level Test Task Pattern), but it's probably overkill if you just need a simple tests README.
