Development record

Twenty-one test packages depend on internal/core/github but have no TestMain hiding the machine's gh login: afterupdate, ahoy, autonomy, capture, embargo, github, ideate, implement, lifeboat, reading, record, release, repolint, report, reservesweep, scribe, site, sweep, update, surface/session and surface/session/web. A test in any of them that reaches the forge reads the developer's real login and tokens, so it can pass locally and fail on CI, which has no login, as the landing body test did in the merge queue for #1147.
