v0.4.2 ~ "Restore the hidden state of tooltips and popovers in production builds"

Highlights

Fix: every tooltip and popover rendered visible in production — v0.4.1 started forwarding the host's browser targets to postcss-preset-env, which then skipped flattening CSS nesting for browsers that support it natively. The attacher styles that hold an Attach::Tooltip or Attach::Popover at opacity: 0 until it is shown are written nested, and ember-cli's production minifier (clean-css) cannot parse nesting: it emitted those rules as top-level & > … selectors that match nothing, so every attachment appeared at full opacity without a hover. Development builds were unaffected because the browser parsed the nested block itself. The preset now always flattens nesting, whatever the targets.
Regression test — tests/node/postcss-build-test.cjs compiles the attacher styles for the console's targets, asserts the flat hide rule is present, and minifies the result with clean-css to prove it survives a production build.
