content: correct a misquotation and restore verified chapter references

Checked against the book itself. The line attributed to AI-dō as "a
drifting run caught in its first minutes costs almost nothing…" is not
in the text; §2.6 reads "A wrong run caught in its first minute costs
far less than one you discover at the end — less of your time, and
fewer tokens." Quoted accurately now, with the section cited.

Restores the chapter titles and links, verified against the contents:
Chapter 3 Software Development (the craft) and Chapter 4 Human and
Agent Disciplines (the climb).
