Development record

The skills chapter says a skill added without adding the skills directory to the payload's include list passes the record gate and is missing from the release (.abcd/development/brief/05-internals/08-skills.md:120-124). TestBundleShipsEveryPluginSurface (internal/core/launch/payload_completeness_test.go:40) fails on a skills/ directory that is neither in the includes nor in surfaceExcludeReasons, and it runs in `go test ./...`, so in preflight and CI. Run against a copy holding skills/foo/SKILL.md with the includes unchanged, it failed. Such a skill cannot land by the normal route.
