v0.8.1: the cost ABP gets its article, with six figures captured from the v0.8.0 tag

One article per release, so the release that added the cost walkthrough gets one. It covers why cost is a property of every call rather than a capability, why the section is written over the runtime universe and says so on every page, why the fifth cost line is the reason the section exists, why a behaviour policy is what a skill runs inside rather than another skill, and why a limit over a number the agent cannot see is an expectation twice over. Six screenshots from a checkout of the v0.8.0 tag on the day it shipped.

Commitgit rev-list -n 1 v0.8.1. The tag is the record: CI derives it from admin/build/version.txt and creates it on the commit whose subject carries site v0.8.1:. The hash is not written into versions/v0.8.1.json, because a release commit cannot contain its own hash and reading it back from the tag made the build produce different bytes on a checkout with tags than on one without.
