v0.12.0

• A rewritten new passes the making module's dynamic import in both of the engine's lowerings (Codex 91): the
  guest-name rewrite passed only $process, so a guest-scoped body's new Function(...) lost its module's loader,
  while the with-scope rewrite passed it. The lowered text changes, so the prepared format moves to
  tabnode-prepared-7: bodies prepared by 0.11.x (format 6, the old constructor wrap) are not found and are prepared
  again, at both scoped runModuleBody read paths. A minor release, 0.12.0 (CONTRIBUTING's rule; the merge that sets
  the version is published as it, RELEASING.md). String(fn) restores both wraps, which only gives back source text
  and never upgrades a stale body's execution.
