Add ignoreEnv generate option during ensureBuild(cmd)

Editor assessment

Add ignoreEnv generate option during ensureBuild(cmd) names a real option but wraps it in implementation shorthand — the ensureBuild(cmd) parenthetical is code, not communication — and why generation needs an env bypass is unexplained. The feat(generator) shell is accurate. The body is the bare house marker [release], which carries no information about the change and replaces the rationale sentence that belonged there. No footer is otherwise present. The subject is decodable with effort, but the junk-tag body and dense phrasing hold the message at acceptable.
