docs(blog): publish testing-guidance null result

[TimeToBuildBob]

Publish “Why my testing instructions stayed the same,” a report of a small testing-guidance pilot. The post explains the 7/12 versus 6/12 detection result, its dependence on one fixture, the failed per-family adoption rule, and the mismatch between the compact control and the intended full skill. It includes the generated Open Graph card.

Validation: independent factual review checked all 24 held-out receipts; scoped source/frontmatter checks, website commit hooks, and the full Jekyll/CSS build passed. Verified the rendered result table and Open Graph metadata and visually inspected the generated card. The post distinguishes repeated trials from distinct tasks and keeps sealed prompts and private workspace provenance out of the public artifact.
