Merge PR #52: no-cache on HTML responses

fix(cache): no-cache on HTML responses — kill stale-page bottleneck</title>
<parameter name="body">Found it. The server was returning HTML with NO Cache-Control header. Browsers were serving stale HTML from their own cache, ignoring deploys. User saw 80s-looking pages because their browser was showing its OWN cached copy of pre-redesign HTML, not the new code.

Middleware now stamps every text/html response with no-cache/no-store/must-revalidate. Every push is guaranteed visible on next page load.</parameter>
</invoke>
