docs(blog): publish The Second Eval and transfer stop verdict

[TimeToBuildBob]

Publishes The Second Eval with the full 0.8B adapter matrix, the 4B fixed-suite gains, and the frozen own-session transfer result that stopped further training: base and SFT both passed the same 1/7 tasks. Adds a dated correction and sequel link to The First Eval, distinguishing observed gains from its earlier size, holdout, and failure-diagnosis claims.

Validation: independent raw-receipt audit for the tool adapter, 4B comparison, and transfer panel; independent editorial review; strict source frontmatter checks; redaction-enabled sync; full Jekyll/CSS build plus a scoped rebuild after editorial corrections; hook-enabled commit; generated and visually inspected OG image. Earlier 0.8B base/markdown/XML counts are sourced from the retained experiment review, not newly rerun measurements. Raw private trajectories and training data are not published.
